Reply to Midi fighter customization in utility

yo I just received my spectra, I've been using mad zachs beta program so far to assign my kits and such.

but I have a question.

HOW DO I CUSTOMIZE MY SPECTRA IN UTILITY?????

I open the program, and load the latest firmware, but cannot get to assign colours and such to each button. Am I missing something? sorry I have been DJing and using analog gear for so long, can someone help me out??!!!
