G'affternoon mtp1032 and welcome to the forums!

when you create the command... make sure to locate 'wow.exe' or the wow application (or whatever its called in vista). if you chose the right program, the fields directly below for the 'wow : username' and maxfpsbk/maxfps will enable. (this is a quick indicator to let you know you are on the right track)

if you need anything more, please feel free to drop me a PM or pop into vyndree's vent (server: sandiego.ventriloservers.biz port: 3860 pword: nether) and i'll try to walk you thru setup.
