Hello, I have an Archos G9 101 tab using the full version of Poweramp. I believe you first have to install the trial version then the unlock full version which really is just a license key. You don't have to launch from that icon just use the original trial version. Maybe uninstall the unlock, install trial version then the unlock version which I believe just runs on top of the trial. Just my 2 cents as a user not a tech support guru. Jason.
