Thanks guys , Im thinking" pro" , just recieved an email from SM tech who said to enter my P7 number to sidegrade to Poser pro . Just hope it works, and that there will be no confussion, like getting the base version instead.  Yep , I know ur gotta trust someone, again thanks for the info and will post if all gos well.
I like the idea that I can get Pro 2010 for free upgrade, and after reading that pro works on a 32bit and can change it to a 64bit renderer when I finish building my new 64bit computer is really great, got 2tera hd, win 7, just gotta choose which processor , mother board , how much memory and graphics card.  As, from reading the advert , I understood it was only a 32bit program, good to read different in these forums............................
