I recently purchased a full version of dBpoweramp, after using the trial successfully for three weeks. When I download the file dmg file using the link in my confirmation email, install it following the instruction to drag the application to the application folder, and then launch it, I get the message:

“dBpoweramp Music Converter” is damaged and can’t be opened. You should move it to the Trash."

I have tried re-downloading the file multiple times with the same result. I have deleted the trial application, as well as the application that didn't install correctly.

I have additionally tried just double clicking on the dBpoweramp icon, (rather than dragging it to the application folder,) and get this similar message: "“dBpoweramp Music Converter” is damaged and can’t be opened. You should eject the disk image."

Please advise how I can get a clean download copy.
