IMPORTANT: Do not change the keylist file password if there is a server currently running that is using the keylist file.
The default keylist file is '/WWWServ/Key/KeyList.Cfg'.
IMPORTANT: Make a backup copy of the keylist file after the password is successfully changed. If something should happen to the original (e.g., deleted, damaged) the backup would then be used.
