When I replace my original Ravenshield.exe with a cracked one I am able to load the game once. But when i try to load it again it gives an error saying that ravenshield.exe has encountered an error. When i check the filesize before loading the game it's 234kb and when i check the filesize after running the game it's 415kb. When i copy the original crack over again, it works and the next time it again wil be 415 when i loaded the game once. I was thinking this was some kind of new protection but i don't know. Can someone tell me what is causing this? (this is the same with other Tom Clancy games)
