So, to summarize: it all works with the new folder, right? In this case, it maybe something wrong with the databases after unpacking/downloading or with the SD card itself. I would suggest to make a new folder on SD card and start populating that. Don't subscribe in huge mass, if you are not going to use it within 2-3 month - regular map updates are expected in that period.

As for "glitch" in startup messages - the last one(s) is of importance for the end user. The whole loading is implemented in a way that it tests for all conditions (and complains if something is missing) during addition of each resource. That was easier for me to debug and implement. So, its OK

In the original state, it sounded that your PM didn't really communicate with the server. Why was that - hard to tell. Maybe server got stuck with some wrong I/O.

Note that you need raster maps only if you use corresponding client - current modRana or Poor Maps (old one).
