Is your tama an oldie now? If it is, the matchmaker won't come; you have to breed with another oldie by connecting. If it's not an oldie, try setting the time to 2:29 P.M, 6:59 P.M, or 10:29 A.M. In one minute you should get the matchmaker, and you have to be quick; I here she only stays for 10 seconds on the v4.
