Since you mentioned the UltraSalon hair by Mehndi I decided to contact her and see if we could figure out what the problem was, and we did... In an effort to make my mat files space efficient (therefore loading faster, and not taking up any more space on your hard drive than absolutelly needed) I had been deleting lines that poser 4.03 doesnt utilize, specifically the 0 0 lines in mat poses directlly under the material file path... So, my products, and mat poses work perfectlly well on 4.03 machines, but can cause a problem for pro pack users apparentlly...I will never again delete that line...and I'm terribly sorry for the inconvience... If you'd like to test it Marque since you're having trouble atm, open one of the pz2 files in word editor and insert a 0 0 line after the texture file path lines...like the following textureMap "Silverleif Studios:Carousel:carouseltext1.jpg" 0 0 If that works for you please let me know and problem will be fixed, thank you for helping me find and hopefully fix this problem!
