After a brake in playing Skyrim I launched steam and downloaded the latest update. I also wanted to take part in Beta Tests so I chose this option in settings. After it, the steam closed and started again and downloaded the files twice. Then I launched Skyrim, however after choosing to continue my game (I play Polish version so I don't know how it is named in English) and after a while of loading the game shuts down. I tried several times, being online and offline and nothing changes. I tried to exit the Tests and I changed the seting but it didn't work.
I use one mod which is called AntiFreezer or something like this.

Hope You will help me : )
