Pulse Cloud License Issues

Okay - I’m excited about Pulse Cloud in general, but noticed one “Bug” with licenses - when the monthly payment came out, it generated a different serial number for me to use in my client sites… And the list of sites I had activated with the old serial number has disappeared…

I need to activate another site today, should i use the new serial number, or will my old one be coming back?

Glad to have fixed this by email contact!
