Local Lan play with GOG version of GD

Hi I am trying to play local multiplayer with the latest patch of GD including forgotten gods. i have 3 pc’s all on the same network running windows 7.

In the past with the orginal GD this worked fine but now no matter which of the 3 pc’s hosts the game none of the other 2 pc’s can see the game to join. I have checked all the usual culprits eg firewalls and nothing is being blocked and we can play other games fine over lan just not GD

Has anyone played local lan recently on windows 7 just so I know its not an issue with the game?

Any help would be appreciated.

No one? I also logged a support ticket with Crate asking if local lan play on windows 7 was still supported a week ago and got no reply. V disappointing.
