Error when trying to activate my subscription


Recommended Posts

I just purchased Nitro pro and was emailed a serial number.  When I try to activate my subscription, it says "-20: Error - Invalid License number.  The serial number entered does not exist. 

What do I do now?

My computer only allows me to save screenshots as Jpeg's and I cant see how to attach that here.  I can email a screenshot if that helps.
