If you are playing on the PC i may have the sollution.
My game was even worse, it wasn't even starting... The game loaded til the Bethesda Logo appears than it crashed..
My solution was simple:
1- Go to your steam library
- Right click TES: Skyrim
- Go to Properties - Local Files - Click "Verify Integrity of Game Cache".
2- Delete all the mods you are using
- "Install" them again
- Run the game.
I did this and worked.

Note: You need to to Both "1" and "2" ..
