OsmandMapCreator crashes out when preloading same or smaller area than what was previous download

[Larry Ly]

I am using the OsmAndMapCreator tool and when I was preloading an area that was smaller than what I already previous downloaded, the downloadTileDialog panel does not go away and it gets stuck.

I have looked in the source code in TileBundleDownloadDialog and in the function downloadTiles() and I can't seem to see where the error would be. Any guidance would be great.
