Go to Home Depot and rent a concrete grinder and a good HEPA vacuum. It's basically an angle grinder with a diamond cup wheel and a dust cover with a vac attachment. Grind off all the glue down to sound concrete then use whatever thinset that Schluter recommends for this application. Have fun and wear a good respirator as well.
