Problem with frequency multiplier in SpectraSys

I am experiencing problems with the operation of the Frequency Multiplier module while using SpectraSys (see the attached file). After loading the file, the simulation works error-free, but after editing anything in the file, I get a Local Error for the multiplier that states: "All input spectrum were lower than the minimum input power level of '11' dBm.  No output spectrum was created." The error appears even though the power from the amplifier at the fundamental is about +15 dBm.

This error only appears if the multiplier model drives another module after it (attenuator or amplifier). If the multiplier directly drives an output port there is no error and the simulation runs fine.

Am I doing something wrong? What can I do to get the multiplier to work right?
