Hello there,
You could try a restart of the Insight manager service, and check by logging onto the System Management Homepage of the server if the repository is also empty there. To go there please look for the Version Control Repository link and see if any SPP or PSP is visable there. If the SPP's and/or PSP's are visible also check if you've selected the right VCRM server, you could have more that one and selected an othrr server with an empty VCRM.
Kind regards,
Andrew
