Warcraft 3 Patch Switcher
Do you have a portable copy of Warcraft 3 and the Frozen Throne? Maybe for whatever reason, you need to switch your current patch from 1.26e to a lower version number for a map to work properly.
Did you know there is a way to switch the patch of the game on the fly? There is a program called Warcraft Version Switcher that can be used to aide with this request. See the two tutorial links below to get started.
