DSP Builder Errors

Hello,

I have a trial version of DSP Builder and I am trying to get a hang of it by building some of the examples. However whenever I try to synthesize any of the `dspa` examples I am greeted by the following error message:

Invalid parameters for S-function 'demo_fird/FilterSystem/DecimatingFIR'. For code generation, S-function parameters must be one or two dimensional nonsparse numeric or character arrays unless the S-function uses a TLC file and has an mdlRTW function.

So my question is, is this a problem with DSPBuilder? Or does DSPBuilder not ship with any synthesizable demos?

Thank you

    It's saying one of the parameters used for generation isn't of the correct type. DSPB pulls parameters from the workspace every time it runs. Perhaps a parameter has changed? I've run DecimatingFIR in most every version of DSPB.
