sprite = Content.Load<Texture2D>("Sprite"); XNA blues
Author
I've been having nothing but problems since I decided to try my hand at XNA.
First off, when I finally got Visual C# to load up and got all the neccessary prereqs (DirectX updates and runtimes, XNA updates and runtimes, .NET Frameworks, ect.) I got this bizzare error stating that I was missing some .dll.
After about 6 hours of searching the internet, downloading 'fixes' that did nothing for me, I finally learn that it's fixed by simply disabling the manifest.
Sadly, that's no where near the worst. Now, what I'm trying to do is do a Pong clone first off. But I seem to have a problem with rendering sprites or textures of any kind. Any program I code with the line
Do you run it in the debugger?
You should see what exception caused it to crash in the debug output window. Probably something wrong with how you add your sprite image to the content.. could be that it isn't found or that the settings for it are different or something.

Trouble installing Visual Studio? DLLs missing in a Visual Studio install? Downloading "fixes" from the internet?
You should really think about an OS reinstall by now. Maybe try Windows 7 RC, it's really smooth.
I chose C#/XNA precisely because setting up a development system is so dead easy. You don't have to walk people through setting up the Windows SDK paths, making sure the DLL runtime is selected, recompiling 3rd party DLLs to make sure they don't suddenly need two different versions of the VC runtime... now it's just install VC# Express, install XNA, done.
You sound a little bit as if, instead of investigating what you're doing wrong, you're just raising your frustration level and put the blame on the tools. Sorry if this isn't true, but this is how it sounds from here ;)
Anyway, back on topic:
- Make sure you added to project within the 'Content' subproject. Otherwise, the files won't be processed by the content pipeline and not copied into your project's output folder.
- The path matters, too. If you create a folder in your 'Content' project named "sprites" and add the file there, you'll have to load it as content.Load<Sprite>("sprites/Sprite")
- Your project wouldn't crash but throw an unhandled exception, containing an error message that indicates what exactly went wrong (which will be shown in the exception window when you run your project in the debugger). If it does indeed crash (access violation or worse), then something's very wrong with your system.
Without further details (error message, zipped example project, whatever) it's hard to tell where exactly the error is.

Yeah, actually I began considering that just after I posted here. Probably going to switch to either XP or 7 today, as soon as I back up all my stuff.

I can guarantee you that this is not a user error on any level. I slaved away at this for hours making sure every last character in my code was right. You are correct about the frustration level though, I had several shouting matches with my screen over this. Believe me, I blamed by self long before the tools, but I kind've eliminated that possibility as far as I can see, so it must be the tools.

Yeah, I made that mistake on my first attempt at it, but I fixed it, and still it won't work

I didn't get any error messages, at least not that I saw. I just got a small window saying "Pong3.1 has Stopped Working" (pong3.1 being my game)like when any program crashes on Vista.
Rate++. You're one of the few cool guys who responds well to criticism. Keep that trait :) :)
Strange stuff. That error dialog should only come up if you ran the .exe on a system that doesn't even have a debugger installed.
Can you put a breakpoint right before the content.Load<>() line and check whether the debugger breaks there?
To see the error message despite this, you could put a try...catch around your Main() method. Not the nicest way of debugging, but maybe it at least gets you a step further:

Thanks for the suggestion Cygon, but In my attempts to back things up for chaning away from Vista, I kind of broke Visual Studio. So I'm going to have to wait until 7 is downloaded and installed to try that (that is if OS changing somehow doesn't fix it)
Visual Studio seems to be a good indicator of there being a problem with your Windows installation. I had a Dell machine with pre-installed Windows where Visual Studio 2008 would flatly refuse to install, and another where I'd get odd missing service messages or form designers failing to start. In both cases I fixed the issue by installing Windows myself, and have yet to have any more problems.

Just finished the transition to Win7 and I am as giddy as a schoolgirl. C# and XNA work fine, my computer is zipping along at a fantastic clip and all is right with the universe. Thank's for your help guys, hopefully I'll never have to speak to any of you again.
I mean that in a good way, of course.
