Modrana has stopped downloading new tiles on my N900. It still displays the cached tiles I have downloaded in the past, and properly positions me on the map, but whenever a new tile is needed, I just get the "Loading..." message which never clears. I have tried uninstalling and reinstalling Modrana, but that did not help. I have tried both Wifi and 3G network connects, and I have verified that the network was functional. No luck. I have also verified that the Openstreetmap site was online and functional when I did these tests. Has anyone else seen this problem, and/or has some idea how I can fix it?
