Do you have any mods installed?
Should run all right with all mods deleted.

Also, if you are running mods make sure to only install the ones that say for 4.0 and don't use the script merger. I have some mods that were just released or updated as of yesterday and did not use script merger at all. Everything works and runs fine.
