Not new, but still screwed... please help

[DamnConscience]

I have over 30 games, but i have not had a problem till the most recent few. I got skies of arcadia (full both discs) talon release, it freezes right when i get to the whale after it asks me what to do, and i download hooligans release for sonic 2, which i know i can't fix and i have to get again, but does anyone here know what to do with skies of arcadia? i saw one post a long way back and no one helped out, please help. Thanks
