Initially installed as per instruction in the first post (Thx for the tutorial

Ran the app, it said cannot find map.
Copied the map to the root folder on the internal memory, no longer complain about missing map.
BUT, the app would attempt to initialize, then closes.
Little X5 icon still appear at bottom right corner of screen;
Click that, and there's option to 'Restore'.
Try that, and it try to initialize and then close again...
Tried reinstalling app, still no joy.
Any idea?
