Step # 5 on that page shows some error messages, and the "Address already in use" and "The attempt to connect was forcefully rejected" point to a port issue. Can't offer much more information than that, but maybe it'll get you in the right direction.
Haven't used Synergy, but Sourceforge's Synergy User Guide [synergy2.sourceforge.net] might offer a start to a solution.
