An internal exception occurred in the call to LoadServers (COM)

I'm trying to move a Foxpro webappliucation with WebConnection version 4.6 to another server.
When I try to run the webapplication I got a "Web Connection Error" with an explanation "An internal exception occurred in the call to LoadServers (COM)"

This is what I have done to set up the application on the new server:
I copied the webapplication to the testserver.
Added the website in IIS (7.5) and added the HTTP handler mapping for the wc.dll file (same settings as the production server).
I installed the Foxpro libraries.
I checked the applicationpool identity's permissions.
I check the configuration files for correct paths

Am I missing something? Can anyone tell me what the error means or where to start looking?

Any pointers in the right direction is really appreciated.

Kind regards,

Harro
