FLY is FUN

Hi,
I purchased FiF on 7DEC14. Now I wanted to download airspace database of Czech Rep. but it said that i did not have appropriate version (not supported already) or i had bad internet connection (I know that connection is good). Then i realised that i have 16.2 version (FiF says that) instead of new 16.90, but there is no possibility to update it in FiF menu nor Google account. I downloaded database mentioned in FORUM here, but it is huge (maybe all world) and it makes my system slow. Moreover some data are old in comparison to database downloaded through FiF. Is it caused by Android 4.2.2.? Do i need newer OS (not enough ROM in my device)? Or do i have to reinstall FiF?
Thanx

You need to open Google play, find FIF and update it. I recomend set automatic update. If your device has not enough memory for update, you have to delete some application(s).

Thanx for answer, but now i have another huge problem. My tablet reseted accidentally, so i lost all my installed apps. Now i want to reinstal FiF, but my google play says that my device isnt compatible with your version. I used it only for few months (yesterday all worked good) and now i am unable to install it again. Unlocker seems to be OK.
Do you have any advice? Is there any other way how to install it?

Has your device gps?
