Help with updating Prestigio

So I need help with updating Prestigio Geovision 7777.

I have put all the new maps(iGO_R3_FULL_HERE_(Navteq)_2015.Q4_Europe) in correct folder and all the licences from "Collection licences for iGO by catymag", but i still get an error saying "cannot open the available map files with your licence". What am i doing wrong?

I have another noname chinese tablet and by just adding new maps and licenses, it worked with those.

Any tips what do to?
