Hi Guys
Thank you for waiting for the fixed build. I think I nearly have it down, but for now I have a dirty fix, so you guys can enjoy my game over Christmas.
* Firstly right click on Retaliation in your game library.
* Click Properties
* Click the Betas tab
* Select the Beta named 'test'
This fixed the game on my machine but if this doesn't work for you please tell me and I will continue to work on fixing the game properly.
