Installed latest driver for Graphics card - NVIDEA GeForce 9600GT

Re-booted PC and re-started FS9

Click on modules tab on FS screen and it shows - unregistered version placard- and can go no further. No FSUIPC.ini found anywhere.

After several hours trying different things I would be pleased if anyone can help.
