Hi all. I downloaded power amp and after the trial was thru i downloaded the unlocker online. Eventually, the updates or whatever made it so i couldnt use poweramp cause it said i didnt have a license.. anyways, i noticed after hooking up my android to my laptop and running a disk defragment on it that the poweramp started working again. Correct me if im wrong, but im lead to believe the defrag reset the poweramp crack. Give it a try and lemme know if it works for you.
