When loading Pathfinder game sources in Pathfinder game mode, select new and then create monster. Select monster Erinyes. This part of the creation works fine. Now go to templates and add the advanced template. This causes more skill points per level that need to be resolved for the existing levels. Some skills are already set to 9 ranks and the creature is 9 HD and several othr skills have 6 ranks. PCGen will nly allow you increase three of these 6-rank skills to 9 ranks even though there are many more skill points left to spend.
