Unable to access text messaging after updating to ICS

I have a Droid RAZR and the stock messaging app just keeps loading forever and Handcent SMS crashes when I access it. I have tried to leave it be and let it load but nothing happens. I would use SMS Backup & Restore (or another backup app) like I have in the past but since the messages don’t load the progress bar just says “NaN 0/0″ and does nothing. This is the only thing preventing me from doing a factory reset/clear data since I have lots of messages on this baby that I need to keep. I'm not sure if the messages have already been deleted, but if they were, wouldn't the apps work? This is just one of my many problems I've been running into with ICS.
