If you are unable to open the Vidcheck Application, the database may have become too large
The reason for this error is because your database is reaching it's limit and needs purging.
You can purge your tasks through the admin tab on the GUI.
To allow you access to the GUI firstly you will need to reset the count and this can be done by following the steps below.
Open "cmd.exe" as administrator
cd to "c:\Program Files (x86)\vidchecker\server\bin" with gfix in the directory
run: gfix -user sysdba -mode read_only nhibernate.fdb
run: gbak -b -user sysdba nhibernate.fdb backup.fbk
run: restore.bat and enter backup.fdk
run: gfix -user sysdba -mode read_write nhibernate.fdb
