Yay. You have a PRC character. And you are correct, the character info will not display properly until it is imported into a PRC compatable module. Do not attempt to import into a noncompatable module. Do not attempt to customize or edit using the Bioware character creator.
This might be good time for a personal disclaimer. The PRC has gone through many versions over the years. My current version appears to be 3.4beta (a long story not worth telling) and thus details may vary. Furthemore I am mostly speaking from memory, not the most reliable source.
So, on to step 2......what Aleron said.
You now need to examine the moduleupdater.exe . This program will install haks into modules using instruction sets called hif files. At this time you probably have only 2 hif files in your hak folder; PRCPack.hif and PRC_oc_fix.hif.
When you installed the PRC onto your computer it should have created a shortcut to the updater. Double-clicking the shortcut will launch the updater program preconfigured to install the PRCPack into any module selected from a list which includes all modules in your modules and nwm folders.
I recommend that you also create your own shortcut to the updater.exe . Double-clicking this shortcut will launch the updater not preconfigured. Instead it will offer a list of all your hifs to choose from. This will be especially useful later.
So then, you launch the updater and choose to install the PRC into the OC. The first thing that will happen is that the program will automatically create a backup of the module. (NOTE: each chapter of the OC is actually a separate module; thus the entire OC is a series of 7 modules) The program will then proceed to do its thing. Before finalizing, it will show a list of resources that will be overwritten. Press Okay. ( I mean, what choice do we really have? I suppose if we were experienced scripters we could try to resolve the issues.
) When the moduleupdater is done you have Neverwinter Nights OC with PRC installed. Unfortunately you're not done.
The OC has several quests, scripts and other situations that are class specific. More to the point they are specific for the original base classes. If you are not one of those classes, it will break your game. To remedy the situation, the PRC group made the oc_fix.
So then, you launch the updater again and choose to install the oc_fix into the OC. The program proceeds the same as before.
WARNING! WARNING! WARNING! If you run the updater a second time on the same module then the new auto-backup will overwrite the previous one. As a result you will have a backup of the OC with PRC, but no backup of the original OC! It is your responsibility to manage backups between installations so that you don't lose modules.
Note: I have seen posts suggesting that the updater can/will install both the PRC and the oc_fix in a single pass. I haven't experienced this but further inquiry might be desired.
At this stage you should now have the OC with PRC and oc_fix installed. Unless I have forgotten something, you are ready to experience the game with the mind boggling multitude of overpowered races and classes... and the frustrating bugs.
Later you will want to install the PRC into modules that already have haks, such as CEP (cringe).
