windows tells me it cant find "America" which is necessary to open zip files, and because milkshape is a zip file, I cant acess Milkshape. Im really bad with computers, but if someone can help me i would really like the assistance-THX

Install WinZIP (or another archiver such as arjFolder, WinACE or WinRAR) to open zip files, if you already have it installed reinstall it; at the moment your file associations are messed up, either because you installed a trojan horse virus, or because you played with your registry.
