ok. i was working on texture. but no matter what i do to it. it only download for my pc(window 8).  but when i ask other if it work for them. i get no...(there pc is unknown). it seem to me that only window 8 can read the file or just my pc when i zip it. but when me and a friend(window 7) put that file together over in dropbox. no problem. just make sure i not play trick with my self. i delete all my texture from file resourcepacks and server-resource-packs, than i log in. it upload just find for me on my server. other not so lucky. can someone tell me what is going on?
