Dru,
The "Data Snapshot Viewer" connection shouldn't be the only one in the list... Do you know if this installation of CCS worked before?
The reason of my question is because it seems you are missing several files in this install... Check the directory below and see if you find several XML files or just <DataSnapshotDecoder*.xml> there?
<CCS_INSTALL_DIR>/ccsv5/ccs_base/common/targetdb/drivers
This will surely indicate a problem with the installation (something went wrong or simply no emulator support was selected) or a possible HD corruption (where windows erased the existing files).
In the first case you can potentially run the CCS installer and repair the existing install by selecting the same destination directory - unless updates were applied after the installation - in this case CCS is cautious and denies the repair procedure to avoid any major compatibility issues. In the second case, a reinstall will surely be required.
Hope this helps,
Rafael
