You couldnt have described what my ps3 is doing and better. Ever since this new update my ascension disc isn't working. I can play any other game fine but when i put in ascension it goes to the warning screen freezes then i have to unplug my system to turn it off. Its not my sytem i just bought the god of war ps3 not even 3 weeks ago, so im getting highly upset
i erased all data of gow, even the data patch(important) below the cd icon then start the game!
u will receive a notification about downloading again the patch 1.07( wait some seconds so it doesnt stuck and press cancel)
now you should be in the menu of gow! go to multiplayer , u will be asked again to download the patches you erased! download them all (it will take a bit) enter again your online code for multiplayer and your done!!
