(adsbygoogle = window.adsbygoogle || []).push({}); :fyea: I finally figured it out. There are SEVERAL, SEVERAL people having this issue. And before you fuckers rage about this being in the wrong spot...where exactly do you expect me to put it? kay:

Anyways, this should help people. Follow this, umkay...

For HACKED systems involving constant DATA TRANSFERRING:[/B]

Go the legit system, and delete everything involving MW2. If you have game saves and shit, get over it. :megusta:
Go to the hacked system, and do the same.

Redo your transfer. (Make sure you have the right patch, and all of that shit)
If you feel the need to, pull out the disc, and lick it. :y: Wipe with a 100% cotton towel, or something, and wipe in a up and down motion. Not in a circular motion.

Yeah. That's all. Delete your shit, and you'll be alright.
A guy had posted this in the exploits and hacks section, and of course it got placed in the answered sections when it clearly did not get answered. Also, to everyone saying it's the disc, or to do a full format, you're stupid.
Also, keep trying to load the game. If at first you don't succeed, KEEP TRYIN'! :y:
This might seem pointless to a lot of you guys, and you might thin this shouldn't be posted, but it should. There are a lot of people having this problem, and it sucks to not know wtf is goin' on. Just delete your game saves on both systems, and then try again.

I have also concluded the following:
If you put the disc in right after playing long sessions of MW3, or some other video game, it decreases your chance of any of this working. So keep in mind, make sure your PS3 is cooled off before attempting any of this if you have the 'kicking back out to the XMB problem.' :y:

Finally! It works again

I'm having the same problem, will try it later.

My fix was closing Utorrent. Never would have guessed that had something to do with not being able to play lol.

Thanks! That helps
