Hello everyone,
I am not used to wirte in forums, so if i made a misstake, don't be too harsh on me

I just bought Skyrim and tried to start it. But during the intro, when i am on the way to my execution, a bug apperas. The gate to the fortres is closed and neither the carriage in front of me nor the one carrying me can enter. I am not sitting in the back of the carriage but instead where the driver should sit.

Before I startet the game I installed a view mods with the nexus mod manager. First I deaktivated all mods, then I deinstalled skyrim and downloaded it from Steam instead of installing from the CD. With that bug the game is not playable and right now all the new patches should already have fixed such a major problem. I am certain t has something to do with the mods but don't know what to do anymore.

My Computer:
AMD FX™-6100 Six Core
8,00 GB
Nvida GeForce GT 630

Mods installed and then deinstalled:
Arrowsmith DV v3
Categorized Favorites Menu v0.1.17
