Crap, what Did I do to my s3?

I tried to put cyanogen mod on my verizon s3 i535 and when it rebooted I get the system software not authorized by verizon message.. I can't seem to get out of this screen but I can get it to load in odin... what should I try now? flashing back to stock? the device says please go to verizon for help but what will they do there?
