Need help with IWT and Click to move.

Hi, Im having trouble getting my IWT with click to move working. I have read the Wiki and even watched the MiRai video on it. Basically click to move isn't working for me. Everytime I hit my keybind it gives me an error saying i must move closer to interact with my target. I can manually enable click to move within the wow client but doesn't ISboxer turn it on and off for me? Please help.
