Selecting Help|CheckForUpgrades with my Xara P&GD 12.7.0.50257 DL Jun 7 2017 takes me to an upgrade which morphs into offering an upgrade to to P&GD-365.

What version is this?

Looking at my Magix Service Center page trying to check which products I have shows me that ALL my products from Xara Xtreme 4 down to a P&GD 12 Trial were apparently bought on 11/24/2017 . I presume that this is 24th Nov 2017

Apart from the fact that it doesn't show my (pretty much consecutive) products back to Xara Studio OR the fact that I have an actual version 12 - not a trial - how do I upgrade (any of the products I have) to the latest version of P&GD ?

TIA

[Edit]
I have found a Trial version of 15.0.0.52382 DL x64 Dec 1 2017 If I register that, is that the latest version ?

(No, this Trial doesn't allow resizing of bitmaps, but I presume the real version will, yes?)
