Ok update: I looked up common problems online and found this chat:
' Ran into a problem tonight where I was being EAC kicked from my own server. I have been playing for weeks without issue, and earlier today without issue. Came back from the store, fired up the game, and immediately got kicked. Repeated this process a few times doing different things that weren't effective (e.g. rebooting). I noticed what I thought was an unrelated issue that certain websites (e.g. 7daystodie.com) weren't loading up like normal, but others (e.g. google/yahoo/msn) were fine. Ultimately, turns out my DNS resolver cache was stale. Opened a CMD window, ran ' ipconfig /flushdns ' and the problem was immediately resolved. No more EAC kicks, and no more problems loading up the website. I don't expect this to be a magic bullet for everyone, but I thought I'd post it here in the hopes that it might help someone. '
So far, it seems to be working for me. will let you know if that changes.
