I am guessing that your copy of Flexi 10 does not have a dongle? Its most likely in Demo mode as VanderJ pointed out above. The same thing happened to me years ago when I bought a cutter and
computer used. There are several non legit copies of 10 out there.
And honestly, If you plan to use the edge frequently, Omega runs the Edge much better IMO ( foil temperatures, workflows, Bleed, traps etc).
