Hi Michael
Thanks for the info.
In the account that prompted the offer of an upgrade - neil(at)yahoodie(.)co(.)uk - I bought the SuperSuite (entire) plus PowerStore and PowerGallery solutions. (In my other - i.e. this - account, I have about 1/2 of the products). I wanted the other rest of the products, and it was cheaper for me at the time to purchase the whole suite rather than the individual items, which I did under the yahoodie address!)
I was confused by the offer of an upgrade , but you have cleared it up.
Cheers.
