Impossible To Grab Gifts Via Fb

All Zynga games work well except for Indiana Jones. Up till yesterday morning all went fine, from yesterday afternoon the following happened. The game when activated on its own is OK. When however I try to grab a gift or request on FB it results in a partial loading, but no other visual but the blue loading stripes.I have let it "load" for over an hour. The same when I try to send gifts to friends. Again,when I then press play it works fine (the game that is) How do I repair this or is this a Zynga hickup ? Attached are 3 screens of what I get to see. Thanx, Glenn Coppens
