Aerospace Blockset demo

Hi,

I am trying to run the 'asbhl20' demo provided in the Aerospace blockset demos. I am able to launch Flight Gear v2.0 successfully by configuring the runscript inside the demo. However, when I start running the model simulation by clicking the 'play' button, I get the following errors:

asbhl20 ### Model reference SIM target (asbhl20_FCSApp_msf.mexw64) for model asbhl20_FCSApp is out of date because the binary information cache does not contain necessary information. This may indicate the slprj directory has been removed or a previous build of this model was not successful ### Updating model reference SIM target for model: asbhl20_FCSApp ### Build procedure for model: 'asbhl20_FCSApp' aborted due to an error. >>

Any help will be greatly appreciated.

Thanks, Arsalan
