CRC Errors in the morning

Everytime i download a game and try to unrar it i get a stupid CRC error the file is corrupt message..... why is this happening to me does anybody know? I tried repairing all the files but as far as i can tell, this only solves those 'unexpected end of archive messages' but its that damn CRC error i cant figure out... please help

Well, lets see. What are you downloading with? Cable, modem, dsl? If your using a modem then stop downloading the games cause they are becoming corrupt do to slow transfer speeds. If your using a cable did you stop in the middle of the download and then resume? That can also cause the file to be corrupt. Basically if it is corrupt it is junk. You'll have to download again but if you didn't do any of the above listed then try a different site, ftp, etc. Hope this helps

please make sure all your files are the right size..sometimes when i files resumes it starts over and continues from where you left off making the file bigger than it should be, if you have that , then just redownload that file...
