Since installing the last 10.0 update, game will not launch, but will launch and play well in Steam. Also, just repurchased Sandstorm DLC and that is only thing that won't run in Steam. Is there a quick fix?
Thanks

I also cannot get OOB to launch after upgrading to v.10. I can catch a brief glimpse of a box with a large red exclamation point that runs and stops before moving me back to the OOB main menu.

See if the game will run in Steam. I was unable to register the serial# for Sandstorm, but I did get a redeem code and now it plays on Steam.

I installed update version 10 today (local version on PC). Now the game doesn´t launch. It does exactly the same as described by DBURN.
How can I repair this? Any fixes?
