So, I've figured out the last problem in my project, only to run straight into the next one.
When selecting "New Game" in the main menu I get a FileNotFoundException from mscorlib.dll
By stepping through the code with the debugger I found that it happens when this function has finished:
protected override void Update(GameTime gameTime)
{
_screenManager.Update(gameTime);
base.Update(gameTime);
}
To be precise, when in debug mode and the current "instruction" is the closing curly bracket I press F11 and the exception happens. I only see that in the output windows though, which says:
An exception (first chance) of type "System.IO.FileNotFoundException" was thrown in mscorlib.dll
No information on what file it was attempting to access or anything, just this line. The game code isn't supposed to load any file at that point anyway, so my guess is that something is going wrong in the framework itself.
Also, the code runs fine on my other system
