Can I export a Hammerstein-Wiener-Model created in MATLAB 2013a to MATLAB 2010b?

Hello,

I have been working with the System Identification Toolbox and developed some Hammerstein-Wiener-Models with it. I am working with MATLAB R2013a. Now, I want to run tests with my models (saved as *.mat files) on a colleague's computer, which has MATLAB 2010b though. The models are not recognized there on my Simulink .mdl file and we keep getting the error:

>> Variable 'xxxxx' originally saved as a idnlhw cannot be instantiated as an object and will be read in as a uint32.

Is there a solution for this issue? Thank you very much for your valuable help.

Kind regards, Rodrigo Ventura.
