WormwoodStudiosBP: Are you on Windows, Zoo? I'm using 2.0.54 version, that's the highest I can install atm.
There might be something blocking the agsgalaxy.dll and Galaxy.dll (if you go to where they are installed and right click properties, if it says "unblock' please unblock them"
If the time played is not tracked and the overlay doesn't come up either, then I believe the issue is that for x reason the game is unable to connect with GOG Galaxy.
I use an up to date Windows 10 and Galaxy 2.0.54, and the playtime tracked properly. The mentioned files doesn't blocked.
