That's a WRPtool error msg, check the icon on the output.log file.
1) did you unpack all the pbo's using Amfali's unpbo 1.51 or PBOx?
2) Your config settings are most likely screwed up.
If you unpbo the pbo's to c:\dump, so you have c:\dump\abel, c:\dump\o, etc, your settings need to be c:\dump in WRPtool.
