Due to change of network card we need to uninstall and newly configured our Flash Operator Panel (FOP2).
We Purchased on may be 13/01/2016
After new installation when we tried to re-run the registration code its shows,
~Serial code already used on another hardware.
~Serial code not available for revokation on this machine!
~Flash Operator Panel 2 - Invalid license for this machine. Demo Mode
then we communicate with the admin of FOP2, they said
"You must request a manual revocation at support.asternic.biz , via email or via live help."
