Game crashes: questions and answers.

Hello, fellow forum users! I was working on a map, and suddenly the game started crashing when loading any map at all! At first, I thought it was due to the map size (50MB), but cleaning it up to 1.5MB didn't help. And right after that, I checked and confirmed that it crashes on any map. The error message is: unhandled exception at such-and-such address in such-and-such cell. Debugging in the studio showed that there's a lack of permissions when reading somewhere. I can't figure out where it is based on the bit name. So, the question is, how can I fix this? The game is a clean, gold edition of Tribes of the East; it's a pirated copy, and it has the Redhaven library d3d9.dll. I'm going to start removing everything, but I really hope someone can tell me the exact cause of the problem to prevent it in the future and fix it now. Thanks in advance!
