Have you tried Re-Installing BBM on your device ? If not then please try it again and see if that helps.But before that please Uninstall BBM from your device for that On your Homesvreen Go to Options > Device > Application Management > Scroll to BlackBerry Messenger > press the menu key then delete it.If device prompt for a restart then do it.
Then perform another battery pull restart like this Device POWERED ON remove the battery wait for a min. then reinsrt it back.Then from your BlackBerry Browser browse to www.blackberry.com/bbm and download the same.After Installing the recent BBM7 your device will restart and will prompt your to login to your BlackBerry ID .
Then have a try.If error appears perform another Battery pull restart and see if that helps.
