I remember Andrew's post but the numbering confused me. My old progamme seemed to be 'newer' than the latest download. It confused Chantelle too when i went onto live chat. Quote from the transcript...........

Interesting, I'm not sure where you would have downloaded a 1.0.8 version from. We'll inquire the development team

But later I was emailed the following.............

The development team had clarified that version 1.0.8 is actually older than 1.0.77. Please download and install 1.0.77 from here, then you can use it to install any new purchases: https://www.pgmusic.com/support.updates.win.dm.htm

so 2/10 for the development team's version control but 10/10 for Chantelle and Live Chat who got rhe answer in minutes.
