Hi both

Firstly, thanks for your replies. I'm always very grateful to people on this forum taking the time to help other users out.

Noel - I used the Live Chat and spoke to a sales rep, who said to try again on Monday when their tech team will be back (which I will do if I haven't figured it out by then).

Matt - I am using Windows and I am up to date with Build 632 and yes, I got that list from the "What Add-ons do I have?" thing in the options.
