Hi I just bought dawnguard , Italian localized version , installed with steam autoupdate , launch the game when finished and the mainscreen loads but it crashes after the menu is about to load ...

Now I do not use anymod apart the one I am doign and I uninstalled too ... so is nothing related to that , I left only the high res texture pack installed, but still nt working .. anyone can tell me why?

I'ts annoyng to buy a DLC that now instead of running prevents even the original game to work ...
