UNZIPPING problem with SeasonPass

Looks like we need a sticky for the unzipping proble, I’m running on Windows 7. SeasonPass completed downloading IPSW file but then froze when it started to UNZIP. And I don’t see any good answer for this. This is a major problem. You can’t go ahead to do anything unless it jailbroken. The software we bought is useless unless we can get SeasonPass to work.
