To whom may be concerned,
I'm a user of DO 10 bought in 2013 from the Chinese reseller ZiQing and upgrade it to DO11 in 2014. I activated two of my personal pcs in 2014 and 2015. Now I want to activate DO on a new pc and cancel registration from one of my old PC. However, for some technical problem, I can not uninstall DO first on that computer. Would you please help me to reset my license status so that I can activate it again on my new pc?
Thanks!
Best Regards
