I bought usb bluetooth device from a shop. It came with BlueSoleil version 6 CD. I installed software from CD. There is no serial number on about dialog box and it does not require activation. Now I want to install version 8 but it asks for serial number. Version 6 does not show any serial number which I could use for version 8. Kindly either provide me a serial number or let me know how to activate version 8.
