Black Ops Loading Problem PLEASE HELP !!!!!!

Whenever i try loading black ops it ends up freezing... Before it would freeze as soon as I press the black ops icon but now I get through a bit of the intro but it freezes around the Treyarch part... The audio keeps playing though, I hear the girl saying " acension... " but it stops after..

Also it's only blackops, MW2 works PERFECT ... But Black ops, keeps freezing on me ..

Version. 1.06

I also tried the PS3 options , #3 Formatting file or something and that didnt help either ..

Please help!!
