Need Help Unpacking Wii Game DL’s From RS

I am having issues trying to unpack the Wii Games I have DL’ed. Every program I have tried has come up with an error saying that the files are corrupt or un readable. Any help on this would be greatly appreciated.
Answer #1
How many games have you gotten this error with? If it’s isolated to a single game and you’re getting errors with every program, logic would tell me that it’s the game that is the problem.
Answer #2
Make sure you have the latest WinRar also, because older versions in some cases won’t work correctly.
Answer #3
Moved from Console Gamez to Helpdesk.
Answer #4
what is the extension of the file??
Answer #5
I have tried multiple games, all with the same errors. I now have the latest version of WinRAR and I am still getting the same errors. All of the file extentions are .zip.### (### being 001 and so on).
