If, on the final step of the Quick Setup Wizard, you chose to use the "(WoW Macro)" under the Party Mechanics section, then your Character Set would've already been set up with an "Active Method" for both Follow and Assist. I don't currently have a reason for why they wouldn't be assigned if you already did that, unless, perhaps, you've deleted the default Key Maps at some point in the past, and then recreated them with the Wizard, but failed to recreate the Character Set in question.
Now, you can assign Active Methods under the "Virtual Mapped Keys" tab of your Character Set, but if you've no idea what you're doing in there (I can't provide a screenshot), then it's probably best to clear your profile (File > Clear), restart ISBoxer, and then re-run the Quick Setup Wizard.
