We'll double check the .rar file on our end. Maybe try to download the .rar file again? It's possible that it got corrupted while it was being downloaded.
Nope I did it again and same things happened
Did you get the 0.4 version?
Yes I even did it right now and it still results in same error
Very strange... Try to use Winrar, if you haven't already. If that doesn't work, then we're not quite sure how to solve this issue :/
