try using AHK on notepad. make your .ahk file, open up two notepad instances and see if it works, else it could be an old version of AHK? or it could be as small as a little typo (a few extra characters generated by a faulty browser when copying to the clipboard that messes with the resulting .ahk file).

or try to start from the beginning and don't worry about the full script from the wiki. make your own little .ahk script that sends jump to all 5x wow windows for example. point is, try and learn how .ahk scripts work and make your own from scratch since you would build one better suited for you/your playstyle than the generic .ahk script from the wiki?
