If you want to break your computer because you're annoyed at losing progress in a flash game, you have bigger problems you should worry about. Also, Eric doesn't read these forums waiting for people to complain directly to him--he's a grown man with his own life. I'm sorry you were banned, but a website ban does not impact your campaign progress. I'm looking at your profile right now and it says you've passed all 42 levels, so I'm not sure that you're being honest.
But if you are telling the truth, my only consolation to you is that PB2 achievements are completely worthless and you shouldn't worry about them.
