The upgrade is a con. There is NO upgrade! After downloading the newer version of the software (version 8), you must uninstall your old software (version 6) before you can install the latest. That means that your details are uninstalled along with the old version and you will have to pay to activate your "updated" version. I purchased five of these BlueTooth dongles in good faith and now I have to advise my customers to go and rip off their own cracked version and damn BlueSoleil  and their money making scam to hell!
