I posted my first problem on Jan 12th.
Now, in following the advice I received from jv16 via the Forum, I have tried repeatedly to uninstall PT 2005. I remove all apparent traces, then I try to download a fresh version. The download does not take place because PT 2005 is recognized by downloading software as already having been downloaded.
When I then try to install PT, the Install Wizard asks me if I want to install the handbook and the translations. It never gives me the option to reinstall PT, which is now always greyed out in the Wizard window.
Hence, I cannot now install PT at all. How can I get past this problem and use the program I have licensed?
Thanks for your help!
