It works now, thanks!

Thanks for detailed explanation! I'll try tomorrow.

That's what I did. But unfortunately after uninstalling v.3 and installing v.2 I got a message about the end of trial period. Before purchasing v.3 I used the trial version of v.2. until the end of trial period. The reason why I want v2 is because I prefer all the UI of my phone to be similar to it's design (black and red combination). So I found Magnolia Icon pack, wallpapers , clock widget as well as Poweramp skin. So the majority of applications are of the same style. Unfortunately Magnolia skin is only compatible with Poweramp v.2.

I've just bought the application and followed the steps in the first post to downgrade to v.2. So I uninstalled v.3 and installed v2 downloaded in advance. Unfortunately after I launched v2 I received a message that the trial period is over and suggestion to restore the purchase. When I agreed to restore, googleplay just returned me the money instead of confirming my purchase. It is important for me to use v2 even though I'm on the latest build of Android. Could you please suggest how could I get working v.2? Thanks!
