Could anyone out there please tell me how to connect the connect desktop client to the E61 handset?

I downloaded connect desktop from the Nokia website. I have PC Suite 6.8 working. The PC Suite connects to the handset very easily.

But when I click connect on the Connect Desktop, it doesn't work. It says "unable to connect to handset".

Any help would be greatly appreciated? I am ready to throw this E61 out after all these problems.

T-mobile usa keeps telling me they can't help. They have put me on the BES plan.
