Help Me!!!!!!!!!!

OMG i'm screwed not only do i have several maps near completeion, i wanna play bnet. when the new patch tries to install i have this

ERROR: unable to load file 'CustomKeysSample.txt' from disk
The system cannot find the file specified.

i don't wanna reinstall my game b/c then all my maps will go down!

WHAT DO I DO?

I don't know what could be causing this, but hopefull it'll be fixable.

Download the attached file and place it in your Warcraft III directory.

thank you SO much! but where is the directory?

If you save your maps somewhere else, I can't imagine why you think they'd be lost by reinstalling.

thanks anyways guys but i just made back up files
