OpenSTAAD in STAAD.Pro Connect Edition

We had a VBA script in excel which worked with OpenSTAAD in V8i edition.

However, after upgrading to STAAD.Pro Connect edition we are having problems with the following line:

Set objOpenSTAAD = GetObject(, "StaadPro.OpenSTAAD")

The OpenSTAAD help file remains unchanged in the CONNECT edition and so I am struggling to work out why this line is not working anymore.
