Ive looked around and have found nothing about this problem so Ill ask people who know best.
Ive had the character creator working just fine whenever Ive used PrC until just now. When I click on the Create Character button, nothing happens. The other buttons work fine, exiting and opening settings but not the create character button, although it does highlight.
The only reason I can think of this happening is because I installed Neverwinter Nights again, in a different place. Possibly some registry problem?
