Hey, I am currently reading 'programming a multiplayer fps with directX' and its all great, however when i try and run the pre-compiled exe for chapter 13 (it HAD to be 13 didn't it) that came with the cd (which is supposed to be the finished game) it loads the window but just says that it has encountered an error. When i compile the pre-written code that also came on the cd with VC++ 6 it compiles perfectly, no errors no warnings, i then run it through VC++ 6 rather than just as an exe and it doesn't work again, this time as it does some vauge debugging and it says: on line 42 of 'i386\chkesp.h' "The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one convention with a pointer function declared with a different calling convention" I personally don't really know what its waffling about but i can usually figure it out by reading online and in the include file, one problem... it doesn't exist, and apparently shouldn't exist, it isn't called in the code or anything. There was a thread based roughly on this posted on here in 2001 but had no answer, why the hell is an include file, that doesn't exist, telling me it has an error in it when im not even calling it?

It stops working after the sound initializes, so there would be a logical place to look, what is puzzling though is that it's the code which came with the book, i haven't changed it so it SHOULD work. I have set DirectX up on three computers now so im 98% i have it up correctly...
