I decided to format my c-drive and have a good clean out, on re-installing poser 11 pro I'm presented with the usual registration, only problem is none of my serial numbers work, on entering the poser 11 serial I get the message:- ERROR DETECTED Serial Number and /or Previous serial invalid. and I have tried the serials fro poser 7,8 10 11 12 and 14 but nothing works, any idea how I can get my poser running?

Getting old and still making "art" without soiling myself, now that's success.
