Can't Un-zip any games.

They all appear to be corrupt no matter how many times I download... I use Flashget and it completes without a problem. I've donated and got 10,000 points, but they're going to waste... I don't like this one bit. Whats up with the corrupt files?

make sure you're using the latest version of winrar.

If you do, try downloading it a different way, inbuilt, another manager etc.

the download manager might be your problem.
try downloading it regularly.
