FLY is FUN

Hi,
I've been using Fly is Fun for a couple of years and "bought it" a couple of years ago - great app!
Got a new smart phone and today it turned into a trial version and needed an unlock program to work.
Did something change? or what do I do to reset the key - I've got a serial #.
Thanks

Hi,
there weve no changes. Did you buy it wia google play or you PAyPal?
If via PayPal, send email with serial number of application - Menu / Tools and Info / About

Hi,

Google Play.
On my old Galaxy S3 Fly is Fun ver 13.32 is the paid version.
On my new Galaxy S4 Fly is Fun ver. 13.32 is the trial version with the same activation # that is in the S3.
The serial # is shown on the S3, but not on the S4

If you pay via GooglePlay, you must install unlocker too...
