Go into minecraft, click "Mods and texture packs" then click default. If you did not install the texture pack by dragging the texture folder into the Mods and texture packs folder then we might have a problem. If you installed the texture pack by dragging the files with 7-Zip or WinRAR into your minecraft.jar then you will have to start up minecraft, but before you log in, click "Options" then force update. THIS WILL ALSO DELETE ALL MODS YOU HAVE ON!

When you open minecraft, where you login with your information, clicks on options, and then force update. You can also just delete the minecraft.jar file by going into the .minecraft folder.

Don't worry; minecraft will download a fresh copy after that without any of the mods installed
