Can't enter skill tree while in beast form

[Kultag]

Hi.

 

I can't enter the werewolf skill tree.

 

I'm in beast form, and I have been in the skill tree, I added 1 perk maybe. I have Dawnguard, after it the Unofficial Dawnguard patch, and over 100 mods. This includes a Lycanthropy and Vampirism potion mod. Deactivating this doesn't help. When I deactivated the Unofficial DG patch, it CTD'd upon load. I remapped the keyboard: the skills menu is now F1 (I don't know what was deafult). It works fine outside of beast form. I tapped the whole keyboard, and nothing. Don't know what else to say.

 

Any ideas? Am I doing something stupid? Could be a mod conflict?

 

Thanks.
