Cause: A table named LogonSession in your Database contains Invalid values
Solution: You will have to zip the 'MainDB.gxdb' file and send us this file (MainDB.gxdb file is located in C:\Sohodox Databases folder).This
file does not contain your physical documents. It only contains
indexing information and some configuration details related to SOHODOX. We will repair the DB and send it back to you.
