Some quick questions to help me find the issue.
- What book packages do you have installed?
- Could you attach a screenshot of the message? (or send me a PM)
- Did it work alright for you with previous versions?
- Do you have any custom professions, spells, races, etc?
- Does the same happen for newly created characters AND for the sample characters provided with the installation?
Thanks for getting in touch, let's find the reason for the error and fix it!
