Master Merchant not working - "RegisterFonts" problem what is htat?

[Viking]

Hi
Can i get help with Master Merchant :

I can't get MM to work again after i installed DLC Gold Road 1 week ago.
I cannot find answers in threads here or other places and i have reinstalled & deleted saved variables, and more and get the same message - also when MM is the only addon that s on. So no other addon seems to be the cause

Full message that shows up now at every charackter log-in:
