WaW not loading when logged into PSN!!

All of a sudden, last Friday, my WaW has stopped loading when I'm online. All I get is the first frames of the war-film then the game freezes. I haven't changed anything with my system. The game loads and works fine if I'm offline, and other games work fine online. Also, it seemed to work okay on Sunday, but has since been freezing. So I'm guessing the problem lies outside of my PS3, anyone have any ideas/experience?

Many thanks for any help!!!

I have the same issue... no luck finding a fix...anyone else?

I'm having the same problem! HELP!!!

ok guys i found a way how to fix this annoying freeze thing i just fixed it today ok what u wanna do is sign offline then you wanna go to multiplayer then go to split screen sign in choose a map press start ok as soon the loadings screen comes up press the ps button fast nd sign in as fast as you can keep on pressing X as fast as you can once signed in it should freeze for about 2 or 1 sec once that is done BAM ur done no more gay freezing hope this works

Edit: sorry guys don't do the thing i posted my W@W freeze again i did the thing i did nd it didn't work it seems like it comes on its owns nd freezes on its own to today it was working fine i turned of my PS3 to go do something came back switched it back on wen to W@W it freezed this is annoying
