GW1980

Where can I find out how to fix the fact that since I reinstalled and started playing NWN2 again, I cannot get my charactor's summon familiar to work. The spell is cast, the animations play, but the familiar never appears. Companions/henchmen's familiars appear but my charactor's familiar does not. I have searched the bioware and atari forums and I am at a total loss where to go to get a fix for this so if anyone can tell me how to fix this please do!
