importing error .sat file to icem
 

Dear All,
I want to import a geometry from Acis to icem.
When i import that geometry, I got following error.

Checking for License...Ok.
Error reading SAT file
Error: api_restore_entity_list: Access violation
Loading geometry file "./20130507 Aero Tower 3-D.tin"

After importing nothing is visible.
I tried to import it again and it mentioned "replace geometry".

What is the wrong with this?

Thanks.
