Why do I receive the error message 'Initialization commands cannot be evaluated' while executing the Output Port block in RF Blockset 2.3 (R2008b)?

I have an RF blockset which consists of the S-parameters mixer and an Output Port block. When I execute the model, I receive an error stating:
Initialization commands cannot be evaluated.

This enhancement has been incorporated in Release (R2010b). For previous product releases, read below for any possible workarounds:
This error occurs when the signal sampling rate, center frequency and the local oscillator (LO) frequency does not satisfy this relation:
LO <= CF - 0.5*(1/ST)
where
LO = Local Oscillator frequency
CF = Center frequency
ST = Sample Time.
fc - lo -fs/2 = -19424000
In the model, if the frequency generated is negative, this error will occur. To fix this error, please make sure you choose values for FC, LO and FS in such a manner that the above relation is satisfied.
