Hmm best bet is to search OR ask at the Bioware forum for NWN2> NWN2 forum
Aside from that make sure you are up to date in your patches ( from memory I think the latest is 1.03.840 not counting the 1.04Beta)
If you are having problems with the patches and auto loader please check the NWVault for a manually nwn2patcher and use google or thieves.net to download the patches which are in rtp format.

And yes it is worth it I have finished the game twice now and am already thinking of another character build <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />

But hey you got any questions don't hessitate to ask and please check the NWvault under NWN2 > UI this brings along some wonderful User Interface modifications and last but not least Have FUN!!! <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />
