Activation error message

This message is coming up when the website renders. If I close out and try to go to other pages too, it is not rendering the page and the same message comes up.

Normally you only need to activate if you have a new license key or if the hardware on the BuildMaster server has changed significantly (a different CPU and/or primary network card), and there is a 7-day grace period after setting a new key before activation is required.

Basically, you just need to activate after setting a new license key - and there is no harm in activating multiple times.
