After running PT X for the first time, and having chosen the option to take a backup before PT X made changes, I found I could no longer access my email program. So I restored from the PT X backup but found that I still had the problem!
This created a big problem having to restore from a system image. I suspect changes were made by PT X to the registry, and not restored properly.
I have not used PT X since. Anyone else have a similar experience?
