I've tried deleted client blob and reinstalling empires. So far Empires is the only game I get this on, and I get it on the only populated servers.
The plans working guys. But seriously, I used to have this issue too. I dunno what solved it, I thyink it just resolved itself after a few months. Send in a steam ticket perhaps.
Wanted to confirm that this does fix some of the cases of problematic steam ids. Procedure: Go to your steam folder (wherever it's installed) > config and delete config.vdf Restart steam (quit then turn on). Steam will then prompt you (on sign in ) to verify that you want to allow you to use that computer for that account (asks you to verify through email). Example path C:\Program Files (x86)\Steam\config
Yeah I can agree with that, I just had to do it when I deleted the config.vdf. But it is an easier solution than deleting the entire userdata folder as I was doing before.
It seems alot of people are getting the invalid userid ticket crap. Must be valve's fault... Deleting config.vdf is a lot easier and also steam stores game screenshots in the userdata folder. Also, it was I who mutilated trickster's avatar in that way.
I think this should get a Sticky. I invited 6 people to join game last night and 4 of them had this problem, one had just installed, the others hadn't played in a while.
