George: Yes, completely uninstall the trial version first and use the CLCleaner software mentioned in one of the "sticky" threads on the first page of this forum.
It is best to download your new version (will take awhile). Problems have been reported with the boxed set.
Download the two files (program & content). Install the program, then the content, then activate, and then apply the 2702 patch, if required.
Let us know if you have any problems, ... or you don't! Good luck. Welcome to the world of PD9.
Have a great day.
Regards,
