Yup....they hit me with the same thing....I recently:
updated drivers
Got new processor and chip
Downloaded the ipad app for commander
I was playing fine and went to work....came home and tried to play and bam....black screen then post I was banned for 1200 minutes and was just told by my clan mates that I am permently banned now by PB. I hav3 been a FPS from way back....I am talking about doom on my 386k pc. I have played and owned EVERY Battlefield game and have never hacked...not once. Please dont give me the canned, "we'll see what EB says"....force the issue...go have them investigate.....this could really leave a bad name in the gaming community....PB is here to protect us from hackers....can't you help protect us from improper bans?
