Thanks for a very well documented error report. This makes my life a lot easier :-) The log file refers to an invalid state (Device lost) which seems to indicate some sort of problem with your graphics card. I suggest reinstalling the driver for the card.

I've got this problem exactly... I really want to play the game, but unfortunately I can't pass this very first screen... my graphic-drivers are always up to date... so I don't know what I could do to fix this for me... would really appreciate some help here. Thank you guys! :)

Thanks for the report, freezing_rain. Well first we should probably look into whether this is in fact the same problem, or a different problem with similar symptoms. Is it possible for you to dig out a log file for us documenting the issue? The file we're looking for is called "output_log.txt" and should be in the "CloudChamber_Data" folder. The easiest way of getting there is to open Steam, right click Cloud Chamber, select "Properties", select "Local Files" and click "Browse Local Files".

NOTE: It is very important that this is done right after a crash.The file is cleared every time Cloud Chamber launches, so it will not contain any useful information if the game ran normally the last time it was launched.

I talked to our programmers about this. They inform me that at first glance it seems that you GPU is below spec. So they are unfortunately not sure we can help at all. However this may not be what is causing the problem. Here is a few suggestions from that to what might be causing this issue, if not the GPU. I hope there is something in here that can help you.

"It seems like a file is either corrupted, inaccessible, or in use by another program. Unfortunately, it seems information about said file is also unavailable. Had it been known, we should have seen it on line 222 in the log. Since it's unavailable, it would seem it's something used by a plugin. Due to the timing of the crash, I suspect it's related to the plugin playing the movie.
The user should make sure that no unnecessary programs are running in the background while attempting to play the game.

Another suggestion would be for the user to open their QuickTime player and attempt to play a movie there. If that also causes problems then we might know where to start.

There are other Steam Unity games that suffer from the same problem, and a suggested method for fixing the issue is to change their Steam Library folder. (View -> Settings -> Downloads -> Steam Library Folders) This would, however, require the player to download the whole game again."
