I have read the ReadMe file before purchase and their is nothing about a guy (male) pack required. Only Poser 4, 4.03, PP with Victoria 3, Head and Body morph packs. Also in the Readme file, Poser 4 users are to manually convert the .jpg Bump maps to .bum format. I have Poser 4-Pro With V3, Head and Body morph backs. I get about 15 of those Missing Male file error Messages in Delta's and ChaVis. I have emailed the Creator of the Product twice and his first response took months and the other response he/She hasn't not replied back yet. I am about to send another email, but I feel he/she is not going to respond. I have purchase another product lately and I feel very proud of it. But my first one (Head Maps), is a loss.
