Was trying to get some .haks installed and noticed when I tried to run CODI character creator I didn't have a chitin.key file. Searched my NWN2 folder and don't see it anywhere. Tried to reinstall it and same deal. Is there something I'm missing here? Thank you for your time.

If there is a missing file from the installation (I've not played NWN2 so don't know myself about the chitin.key file) then I'd first suggest re-installing the game (outside of Program Files just to be on the safe side) and if it still isn't right, I'd raise this with GOG support. It may be that their installer is indeed missing the file and if they are notified about it they'll get it fixed. Should you need to contact GOG support, use this form:
