Hi Joanne
There are a number of options, but the most surefire one is to reinstall Ledger. Make sure you are sitting at a workstation when you reinstall it to your server. Do not install Adagio while sitting at the server.
The other options involve asking your Adagio consultant about a utility that re-sets the Report Table drive, or installing any Adagio upgrade dated March 2011 or later. The latest upgrades deal with this Report Table error message directly. Soon this error message will be a thing of the past.
