RWWGuard 2003 Activation Fails with the error "Server Response: Invalid activation start date."
This issue is caused by a mismatch between the way that RWWGuard 2003 and the RWWGuard Activation server calculate the activation date and time.
Download the RWWGuard Activator tool from our download site. Run the tool on your SBS 2003 server and enter your RWWGuard key (including dashes), then hit the Activate button. After your RWWGuard 2003 installation is activated, you can log on to the RWWGuard Manager to complete the RWWGuard configuration.
Note: Make sure to note the expiration date displayed by the tool and mark this down on your calendar so that you know when you need to renew.
Any copy of RWWGuard 2003 activated after March 1, 2011.
