recently, an excessive amount of ps3 users who want to play mw2 continually experience the game crashing after several seconds of it loading up. After constant times it happening to me, i finally figured out why it was happening. There is nothing about it being ip banned or any other theory other people have. It is as simple as flicking a switch to fix.
It might sound stupid, pointless, unbelievable, but the simple solution to stopping it is by restarting your router. If you don't believe me, try it for yourself. 9/10 times it has worked for me, & i constantly got the crashing problem. If it doesn't work for you, don't be a whiner & -rep & groan this post. Try it again in 10 minutes.
If someone can make a video of themselves doing this method, it will show people that this sin't some kind of scam, or whatever anyone else wants to believe.
