blizzard.j not found in installers directory

Hi ,

I'm trying to install AMAI. I read the manual. it says to create a subfolder in the maps folder in WC3

to i make maps\AMAI[someversionnumber]

when I run AMAI .exe it says blizzard.j not found in installers' folder
this don't make sense coz I've put a copy of blizzard.j there and in warcraft installation folder and in several other folders. it still stubbornly tell me blizard.j not found.

any idea why?
