What is the meaning behind 'XX maps failed to download'? I have some maps tiles, scanned and cut into 256x256 pixel tiles, in a repo and I am using a .../%d/%d/%d.png structure for the repo. I even have a copy on the SD card using file:///media/mmc1/map/1113A/ etc.
These tiles are visible *when I browse to them!*... but will not 'download' to MM. MM reports 'Processing xx maps" but then fails. The screen remains black whatever I do.
I have tried going to a lat/long within the map tile space but no joy.

Any help gratefully accepted.

PS. These are nautical map tiles which are apparently greatly desired.
