I'm not having any issues with the AH004 hair. Did you delete your .rsr file in RuntimegeometriesRoyloo? It may have gotten corrupted. Even if you reinstall the hair, it won't help, as the .rsr is created on the fly. Close Poser, delete the file, then open Poser back up and try again. Thanks a lot CarolineG and Royloo! This is very much appreciated!
