DrRerNate nuriag Same here. According to the news tab they updated servers and had an issue that the newest version of the app couldn't connect anymore. Supposedly fixed that issue, though. But I've got the newest version and can't connect, so...
rustylantern I also have this issue. I tried everything: clearing my Steam cache, uninstalling and re-installing TtA, rebooting. I am rumming this app via Steam on my MacBook. I have also checked that I have the latest OS updates.
