Windows 7 EAW Forces of Corruption Problem Thread

Hello everyone. I followed all of the instructions on the main page exactly, and the game worked perfectly. However, the next time I went to play it, the loading screen pops up, then I get a message saying it has stopped working. I have the steam version of the game, and did the work around for the launcher, with the 4gb patch. As I said, it worked the first time, but won't any more. Any ideas?
Thank you in advance
