I'm having this problem too....and I really don't feel like uninstalling...clearing appdata doesn't seem to help either (not that it should, since the location of those files has changed)...

Would be useful if Ironclad could confirm if this is actually the case (borked beta in which case I will wait for a supplementary update) or if its a Steam Update/local issue...and if the only solution is to fully uninstall & reinstall.

I have the same issue as OP, have tried backing up local game content and restoring, no joy, and have tried flicking between "keep game up to date" and "not" to see if I can force Steam to re-update...no joy.

So, with my amazing 3mb internet connection I am seriously hoping I can avoid a fresh install and reinstall

Brew.

It is at the very least a widespread issue, which we'll most certainly be looking into as soon as we can, so don't stress out over trying to find a client-side solution.

My friend and I have the same problem. Well done Stardock! I understand it is a beta but why rolling out an update without proper testing of the basic things?
