RE: I have RF3.5 would like just the 4.5 softwareve the controller
They don't sell it without the controller. If you want G4.5, expect to pay $200 for the program, another hundred for expansion packs and a thousand dollars for a computer that runs it. Oh yeah, it still waon't run right anyway.
Get G4 if you can, G4.5 is an unfixed beta rushed to market for $$$$$. Sleasy company IMHO.
