I PURCHASED LIMEWIRE PRO VERSION 5.1.2.1 EARLIER THIS YEAR. NOW WHEN LIMEWIRE LOADS UP IT ASKS IF I WOULD LIKE TO UPGRADE, WHEN I TRY TO INSTALL IT NONE OF MY INFORMATION REGISTERS. I PAYED FOR IT NOW I CANT UPGRADE IT OR ACCESS TECHNICAL SUPPORT. I'M NOT SURE WHAT TO DO. IF ANYBODY CAN HELP I WOULD APPRECIATE IT, THIS WHOLE THING IS REALLY FRUSTRATING!!!
