Well, cloud settings would probably be a good thing. In the meantime, however, you can many copy your client settings to different computers. How do we backup our settings?
Also, you shouldn’t have to be changing your settings every time you play. Sounds like something is wrong. Unfortunately, I’m having difficulty finding anyone else with the same problem. So, I dunno. Make sure that your settings folder isn’t set to read only. You can also try using the free version of revo uninstaller to uninstall, and then reinstall the game. Past that, I’d file a support ticket.
And please come back and tell us how you fixed it. Might help the next guy with the same problem.
