After the recent patch (1.6.1.1) I am unable to launch multiplayer.

The error message tells me to shut down the game, launch GOG Galaxy, and then start multiplayer.

However, I DID launch the game from GOG galaxy. What do I need to do to fix this? I need my anthromorphic Turn of the ccentury critter multiplayer mayhem fix.

Is anyone else having this issue? I saw this other issue with GOG multiplayer where GOG hardcoded assuming the game is installed in C. My C is a fast SSD only boot drive, so I don't put games there.

Has this worked for anyone? Is there a workaround?

Apparently C drive doesn't work. Has anyone gotten multiplayer working recently?

I saw the changelog and the latest version is 1.6. Maybe you can only use that version with GOG Galaxy support for multiplayer... Didn't check if I can play multiplayer. I usually play singleplayer all the time for almost all my games.
