I've been away from simming for awhile, and after upgrading my rig I wanted to get back into it - especially after the recent release of REX Essential. I managed to dig up the original email I received that contains my product key, but when I paste it in the appropriate field after starting RC (as admin), the program exits (as it's supposed to), but when I restart RC, it behaves as if I never entered the information. I tried the default install to C:\Programs Files(x86)\rcv4x, and also c:\rcv4x but no luck in either case. I'm running Windows 7 Home. Do I need to re-register to get a new key or what?
