If you are receiving this exact prompt when you launch your Melco software:
This indicates one of the following situations:
Condition: If you have recently upgraded your software to Melco OS v11 or Bravo OS v11, you should've received a Virtual Serial Number (beginning with M201- or B201-). The prompt above indicates that you still have a USB Security Dongle from an earlier revision of software plugged into your computer.
Resolution: Remove the USB Security Dongle and the software will prompt you to enter the new Virtual Serial Number provided to you on the back of the installation DVD case and/or via e-mail.
Condition: If you have recently upgraded your software to AMAYA OS v10, you should have received an Access Code via e-mail; sent to the e-mail address that we have on file in your Melco customer record.
Resolution: Enter that Access Code to upgrade the programming on your USB Security Dongle to make it compatible with the updated version of AMAYA OS.
Condition: You have installed a higher version of Melco software than your USB Security Dongle supports.
Resolution: Install the correct/compatible version of Melco software for your USB Security Dongle.
Condition: You have inserted the incorrect/older USB Security Dongle for your Melco software. Resolution: Locate and use the correct/compatible USB Security Dongle.
