Topic "Adding an attachment" a message from DCEOIT

Hi,
I am running RDM version 9.1.0.0 Enterprise edition with RDMS version 1.1.3.0

When I try to add an attachment to any of my remote desktop or Putty items i get an error indicating that 'i cannot connect to the data source and if I want to go in offline mode' I am definitely in online mode when i try to add an attachment.. When I select no i receive the following error (see attached).

Please let me know what i can try to do to resolve the issue.
