HyperFireXD FORGET WHAT I SAID!!!!!!!!!!!
I already saw the error; apparently, MediaFire doesn't have the symbol and changed it to another one when uploading the file. Try changing the skin's name to this one without the parentheses. (~-gmtl_t6_wpn_smg_peacekeeper_col)
awesome its working now. but now that i think ab it, i did tried to download a few of your skins before (like the galil for zm) but they never did show, maybe this name issue applies there and a few other skins too?
