SableSteel, do you know when the online version will stop being just a black screen?
We don't have many contributors working on this port of ClanGen currently, but the issue you're having is pretty well-known. You can try and just wait it out as it will occasionally fix itself, but the most reliable way to fix the issue is to clear your cache! This will unfortunately delete all current Clans you have though. A quick google search can show you how to clear your cache if you're unfamiliar with the process.
