You have the directory set correctly. It would appear you have the same issue I did a while back. You're not doing anything wrong, but it's the mods that are causing the problem.
Some mods haven't been updated for this new version and whatnot. Check the date on when the latest update came out, then check the dates for your mods. Anything before will probably just crash you. Use up-to-date mods, and see if that fixes your issue. It fixed it for me.
If that doesn't fix it, I will try to further research your error, and see what I can find.
