If you run this mod as normal, you get black backgrounds for the skill pages, and possibly other issues.

I managed to get this mod to work properly by doing the following:
- open steam
- rightclick on "titan quest: anniversary edition"
- click betas
- click "anniversary_ragnarok"

This might interfere with your shared stash though, haven't tested that. To be safe, make a mule character and load your shared stash onto that character. But this mod works properly this way.
