Memory Acess Error PLEASE HELP ME!!

Happens with every single 3d program I write. It works fine in the IDE, but when I create an executable and run it, the memory acess error pops up. PLEASE HELP ME, I have a deadline for my game!!!

Please note--I have two laptops and one desktop. The desktop and one of the laptops both have Windows XP. The other laptop (Which I use extensively) has Windows Vista.

This is usually caused by media files not being in the right place, and so not loading.

So the 3d models are NOT packed into the executable?

Not unless you're using a separate file packer, no.

ok, thank you!! you just saved me from migrating to C#!!!

correct me if I am wrong, but going to C#/C++ would not do you any good unless you understand file structures.

EDIT: Strange. I'm sure I wasn't posting here.
