Suddenly got this error. What is going on? The license key is only used by me...

Holy moly. I'm having this too all of a sudden. Is the license my Code Canyon purchase code from 2014?

No idea, but if you get this, follow the KB article and reset your license.

Not sure whether resetting the license or reentering the license, but it fixed the problem.
