To cut a long story short, I moved my SAGE library to another drive but the move failed due to a corrupt file problem.
So, I've had to completely re-install from version 1.5.1 to the current version.

Silly me, I missed out 1.7.1e so my question is:
Have I missed anything or is it all there?
(First time I did it I missed another version out and didn't install the time designer presets).

Interestingly, I was never prompted to re-authorise so I assume there were some hidden files somewhere that I didn't delete prior to installing.

I hope to never have to do this again, but an uninstall routine would be useful Eric.

Anyway, look forward to (hopefully) some reassuring replies.
