Dear BD Technicians:
Can't express how i was amazed to see upgrading from BD 2009 to BD 2010 at no cost. However, as i followed the procedures described in the top-listed thread, all is ready for inputting my serial number for BD 2010, and what surprised me was that it showed "License key you have entered is invalid". and now the software is running at evaluation mode.
The license key was purchased in China for a three-year non-stop upgrading service. and My registered BD account is "<removed>".
I'm now wondering whether this free upgrade service has a bias for the above-mentioned region.
As My desktop is running with Windows Seven, an BD 2009 is no longer compatiable with Win 7 any more. Pls. do me the favor to tell me how to resolve the problem.
Thanks very much.
P.S.: BD account mail address is feasible if you got any resolution, thanks again!
