It just started doing that to me, after it kicked me from server saying it can't connect to vac server.
idk empires is the only game i need it for and so far it only didnt work when it didnt work for anyone (this one patch where it was broken for a day or two)
It sensitive, you need to play with it. Sometimes I have to keep refreshing for the servers to re-appear. Usually depends if steam is hiccuping or not. Or as sitka calls it. Gabe sitting on the server.
