GOG.com version of Neverwinter Nights Diamond Edition (version 1.69); CEP 2.4; PRC 3.5. Windows 8 64-bit edition.
I've managed to get PRC to work brilliantly so far, but I've noticed that after creating a Silvanesti Duskblade, it won't let me complete the Prelude missions in the Academy. In fact, after I finish off the combat training portion and speaking to the trainers there, I'm told that I need to complete the duskblade challenge. I tried visiting the spellcasting trainers, but they all tell me that since I'm a duskblade they can only give me the basics on spellcasting. The guard at the door to the Graduation Chamber tells me that he won't let me through until after I complete the combat training (which I already have).
I've tried both saving and resuming said save game; even tried playing all the way through the Prologue without saving but still get the same result. I can get through with a "standard" character class (Drow cleric), but not with a "hybrid" class like the Duskblade.
Any ideas?
