IE3D - finite substrate

Im trying to model a patch antenna on a finite ground and substrate.I followed the manual in creating the finite substrate.But after the meshing when i try and simulate, it gives me an error message.
"remove current graph from list
remove current graph from list of simulating finite dielectrics"

Could someone tell me what it means?

Hi:

It is a corrupted message in some older version of IE3D. The correct message should be reminding you on update the license. Please contact support@zeland.com for upgrading your license. Regards.

Hey i think mine is an older version. However i was able to export the geometry to FIDELITY(it does the finite substrate beautifully).

Thanks a lot !

does the finite substrate option work on the trial version.I got a different kind of error that said "dynamic allocation failed" or sumthing like that.

It is due to not enough RAM.
