Hi Stilkdog,
I didn't actually do anything to fix the issue for Tripwire when a couple of them ran into that. I think your client is just in a bad state. If the suggestions from John don't resolve your issue, could you launch your console, then try to install the game. When it fails, you should get a bunch of spew in your console. Copy & paste that into an email to me and I'll be able to better identify where it's going wrong on your client. I haven't been able to duplicate the issue, so I suspect it's something simple with your client state, but I won't know until I see your console spew. You can email me at
