Their was a code change awhile back, that may have caused in "incompatibility" issue, but from what I know, it wasn't with the app, it was just that the game couldn't update itself. it required removal of old install, and full re-install.
Okay, I'll try a full reinstall. Thanks for looking in to it!
I had to click the cog icon and select which version (free or paid) and now it's installing. Thanks again
