Well that sort of helped but now i cant see any modified textures when i play mc, alltouhgt i modified them, should i try modify them again or what?
Have you -
Put the zip file in the texturepack folder?
Selected the texture pack in the title menu? (Mods and Texture Packs)
~Also you don't have to have all the files in the texture pack. The ones you don't replace are set to the default textures, (only works for missing files, if you don't have a part of the file filled in, the texture will show up as nothing.)
Have you tried patching your Minecraft with the latest version of MCPATCHER?
