I uninstalled, reinstalled, verified  NWN Diamond (GOG) the installed PrC and nothing else.  Then CC complained that I did not have a portraits folder.  So, I fixed that and it stopped crashing and complaining about it.  But, when I pressed finalize after creating a complete character it took forever and produced no results.

Tried Leto but it doesn't add the right feats.  You have to do that manually.
