Error in Flightgear/Simulink interface

Hi,

I've been working with simulink and flightgear for some time, using Flightgear 0.9.8 to show animations driven by simulink.

Now, I'm upgrading to Flightgear v2.0 with Matlab 2011a, but there's a problem with the "Send net_fdm" block (in aerospace blockset). If you drag this block to a blank model and try to edit some parameters (or simply click OK without changes), there will be an error regarding number of parameters.

I've managed to edit the "Send net_fdm" block mask and delete one of the parameters. It works when I select version 0.9.8, but Flightgear doesn't receive anything when I try to send to v2.0.

Any help is much appreciated.
