Now I usually don't post on forums, but I have to tell you that (now this could be wrong, don't blow up) the Game Maker 7 that everyone supposedly "makes all their games" with is a virus.
It started when I downloaded it and make an .exe file to share with friends. Immediately after I did this, I couldn't use Rosetta Stone on my computer. Immediately after I deleted (and double-deleted in the trash bin) Game Maker 7 and everything related, Rosetta Stone worked just fine.
Yoyogames? thats weird cause i never got a virus when i got it from Yoyogames. even my school's computer's got it from Yoyogames and it works fine. no virus. maybe you got a bad copy cause i never got this problem on Yoyogames.
