I just did a clean install of Twilight of the Arnor from Stardock Central, without having the beta version installed or such. Everything works fine otherwise, but when I set up a new game, the create custom race button on the opponent setup screen is disabled. Has anyone had this problem?
Resolution: If you had the beta, make sure you delete the gc2twilight directory from my documents\my games\. We will issue an update later this week that will automatically remove the data for later installs.
