What did you "buy"? Pentax software was never available except w/ a camera purchase... Also what CPU are you using? What operating system?
Also if your very daring, go to regedit and remove Pentax from the hot key current user:software: pentax and hot key local machine;software;Pentax. Then reboot and reinstall... Back up registry first..
be very careful. and do it at your own risk....
