MILES to GO || before I sleep

staplerx, ohsupervinchan, or richlikesmaids: I finally got Stepmania Complete torrented. It was in SMZIP format, but the SMPACKAGE program didn't want to open it. I tried opening it with StuffIt, but it always tells me that "Archive Verification Failed." It runs the expansion anyway, but it never finishes.

;_; HELP! I have this 854MB file of DDR-ness, and I can't use it!
