I just installed LV-DSC 8 on my PC and I am trying to view some historical data through the Historical Data Viewer in MAX.  The historical data is on a remote PC running LV-DSC 7.  I can connect to the remote PC and see the database name, but when I click on it to view the tag names, I recieve the error message "Unable to access citadel edit log.  Database files may be read-only or invalid".   Does anyone know what causes this type of error?  And what is the 'edit log'?
 
I verified that the files are not read-only.  I can view an example database that ships with LV-DSC 7 on the same PC, so the problem seems to be specific to this database.  Strangely I can read the database without any problem locally or read it from another machine with LV-DSC 7 so the database is not completely corrupted.  Thus the problem exists only on this database and only when viewing it from a LV-DSC 8 machine.  
 
In LV-DSC 7 is there a way to run a "repair" routine on the database?  I wonder if detaching from the database and then reattaching might help.
