I had this trial version before and it expired then I uninstalled it. Then, I installed the new full version and the problem now is after completed the installation, when I try to open Cyberlink PowerDVD 11 Ultra by double clicking on the icon, it gave me no response. I can't even open this software, what is wrong with this? Is there anyone know what is the problem, your thought will be deeply appreciated. P/S: I've tried to re-install few times and the result still the same... Pls help me! Thanks!
