Unable to open Blackberry Messenger

Hi I have the BB Storm Verizon Unlocked with OS v4.7.0.75. At the beginning it works perfectly, I was texting with my girl through BBM and all of a sudden the phone reset by utself, I turn on agian thinking that this was normal. Everything was ok, til I tried to get into BBM again. I�m able only to put the BBM icon in blue color, buy I�m unable to open it. I already tried to reset the phone by taking the off the battery, I tried already to update the OS again and again with no luck.

Thanks.

Try removing the application through the desktop manager and then adding it back.
