Lisp Error loading extension COM

Hello, I have been using autocad and with it I have a few lisp routines that where created by a previous user in the firm. I have downloaded the free 30 day professional trial version to try it out.

I press the load aplication and select the lisp routine and it loads without erros..

To run the app e write "sap" and it starts fine and appears the main menu.

Now I have ti choose an option to continue (7 possible options), everything is normal this far.

When I chosse an option (any one of the 7 possible) the program gives me an error "Error: Failed to load COM extension."

I have loaded the print screen, but it is Portugues

Thank you
