User blog:KING777/Weird happenings in MW2 multiplayer

Hello in MW2 PS3 some weird things have happened lately. One day it TDM I could not use my killstreaks after getting them, then I could not defuse a bomb in Demolition. What's next? IDK what's happening. It's either my game, or my PS3. There could also be something to do with the newly discovered hacking device for PS3. Any ideas? Has anything like this happened to you?
