Hey, I just bought Postal 2 and I tried starting up Share the Pain and I got an error that prevents me from leading up the game. I'm running this on a 64-bit Windows 7 Home Premium. Any help would be appreciated.

Have you checked the download to see if it was correct? You can find the hash on the gog wiki.
Is there any antivirus that could have prevented copying the file over?

It's probably not Win 7 64-bit as I'm also running that on an HP computer. :)

Thanks, that was the problem. It must have not downloaded properly the first time, but it works perfectly fine now.
