GPS Data Logger Software - BT747

Hello

I am running BT747 (BT747_2.X.1685_full.zip) as desktop application (no Java Webstart) and I have no proxy configured neither in the system (Ubuntu) nor in jre/lib/net.properties. The problem is that I can't see any maps in the map view. In the console I see many instances of the following exception:
