If you were configuring dMaintenance with a dCloud subscription, this applies to you. You MUST reconfigure and redistribute dMaintenance v2.4.8 and better. Previous versions will have issues when updating their configs from dCloud.
The issue is with the installer, it will not create the appropriate registry key to set the client identifier that can disable dMaintenance should you disable it from dCloudConsole.
I believe everyone affected has been notified, and I apologize for any inconvenience.
