jankratochvil: I'm not having any trouble running modrana. I want it to use downloaded tiles instead of always refusing to show a map unless it has a connection. (I do field work, and there's often no signal, but it would still be nice to have a map on my n900.) So I don't really need to re-initialize, do I?

What I want to do is see maps when there's no connection. (p118 has details on the error messages I get.)
