That's a bug -- I believe the workaround posted was that for some reason the Char Gen is looking in the Core/Races folder and not looking correctly into the User/Races folder. I think you can place a copy of your .rac file in Core/Races and it will work for you. Let me try ...
Yep, that worked. I copied a file Vampire, Human.rac from my User/Races to Core/Races and the generator works fine that way. The problem, now, is that race appears twice (once in the A-Z list for the core/MM races and once at the end of that list with the custom races) -- so just be sure to pick the right one when generating.
Note that this is a temporary fix until the patch comes out.
