Error during command authentication.

Error - unable to initiate communication with LISTSERV (errno=10061, phase=CONNECT, target=127.0.0.1:2306). The server is probably not started. I have a MacBook Pro running System 10.6.4  Using FMP 10.0 v 3. When I try to start up IWP using the practice files that came with the Filemaker Training Solution for FMP 10 it crashes the program. Can any one help on this.
