Game crashes when I try to open next page of skills

I have a problem in the game, if I press K (skill window) and click on the small right arrow in the bottom of the window the game gets a lag and then i get a crash report from windows. It happened when I bought 2 lvl 110 mage skills at Skill Master Ruby. After it I couldn't open my next page to see my other skills and open my new skills , so I can't see my new skills if I buy the next level version of my skill, I can't see my new skills and I can't use my skill points for the skills on the next page.

I hope sum1 could help me out
I can't wait!

Did it happened after u patched?

exactly the same problem I have with my fighter also ..
