I registered just to reply to this post.
Yup, I have the same problem (and have been stuck for over 2 months) and got NOTHING from tech support when I logged a call. I have a character who has full allocations of Blade, Shield and Repose and and I have just levelled up - I cannot allocate the point anywhere and I cannot exit the screen. See the attached screenies for what I mean.
I have tried going back to older saves, but they all ultimately end up at the same place. Tech support recommended I start again - very disappointing in my opinion, and their interest in trying to solve the problem was pretty much zero.
If I could I would return the game I am so frustrated.
If anyone can provide useful insight into how to fix this I would be very appreciative.
