Sometimes when you try to fast foward the time, it doesn't work for some reason. My Tama is 7 today, and I tried to fast foward the time to the Matchmaker times (10:30 AM, 3 PM, 7 PM), and it didn't work. Then, about 1/2 an hour ago, at 7:00, the Matchmaker came! It was odd. So, maybe you should just wait and not try to fast-foward your Tama. The MM will come eventually, maybe at age 8.
