MAR Transport Configurator ERROR

Hello CRM Mobile Guru's,

I have installed the Moblie Repository Server on a windows server 2003. The .Net framework release used is the 2.0

We have installed the SAP CRM Mobile client 7.0 SP4.

When I configure the MAR Transport Configurator for CRM connection server, i have git the followong error.

"Failed! Could not establish connection to "CRD".

Details:

Could not load file or assembly 'SAP.Connector, Version=2.0.0.0; Culture=neutral, PublicKeyToken=50436dca5c7f7d23' or one of its dependencies. The system cannot find the file specified

I have one question. Is the SAP Gui mandatory to use MAR?? I think it is note a prerequisites of the Mobile Server Reporsitory.

If you have an idea? please advice.

Best regards.
