Moved to new thread, beta posts are usually locked on release of the final version.
It might just be an oversight of the reported version, if you go to Menu>File>Import> do you see Google photos… ?
Either way can you state what platform you downloaded for, Windows, Mac, Linux, Anything.
Try a complete uninstall: Uninstall, then ensure that no files are left under C:\Program\JAlbum. Now reinstall. Don't worry, this won't affect your existing projects and settings.
I experience the exactly same problem - I installed the update via the mail I got - but it's still 37.5.6!
Then I downloaded the file once again from this site (and the properties says it's 3.7) - installed it... and get the option to Edit, Repair or Delete. So It is the same version as the one they're linking to in the mail! I have restarted my desktop PC.
