Comment on WHDLoad Support in FS-UAE Launcher by Loren McDonald

I have followed the above instructions: pointed the HardDrive entry to the zip file (the emulator fills in the appropriate .slave file name by default) but when I try to run it it doesn’t work – No WHDLoad spalsh screen… it just dumps me to a CLI with the message Unknown Command IF.
I have uninstall and reinstalled. The first time it runs after a fresh install I see the notice that WHDLoad is being downloaded, then never again.
I’ve got to be doing something wrong… please help.
