I'm having trouble getting it to run, though. I get a "failed to download date file" error when I start the game, even though I do have an internet connection. I tried disabling my AV firewall but that didn't help.
I am having the same problem. I've tried everything I can think of but so far haven't been able to fix the issue. If you figure out what is causing your problem could you let me know. Might help me solve mine. I think I had a similar problem with Elemental beta's before, never was able to fix the problem so I just played sc2 beta instead lol.
The solution was simple: I never realized that, unlike Steam, Impulse doesn't log you in automatically. So all I needed to do was to log in ('change log-in' on the top left preferences icon - I think it should read 'log-in') and the game started just fine.
BUG REPORT: I found one bug so far: I was in a tactical battle and my sovereign was struck down on the battlefield, leaving Janusk alone. Well, the battle kept going on with the AI bandit running around seemingly randomly. Eventually, the bandit just fell to his knees and died for no apparent reason. The battle ended with a victory for us, with my sovereign alive and well on the strategic map.
