If you can't see the maps when connected to the internet, then you seem to have a more basic problem.

It goes without saying, but I'll ask anyway. You do get a satellite lock, don't you?

First, I would change the map configuration (only set 1 layer, and change the map provider to something else, for example Google Maps).

And if what pichlo and I recommended doesn't yield results, then uninstall and install modrana again.

1. sudo gainroot
2. apt-get remove modrana
3. <Move your modrana data folder somewhere else, or delete it>
4. apt-get purge modrana
5. Go to Application Manager and disable extras testing and extras devel repositories.
6. apt-get install modrana

(Note: 5. is optional, but I recommend it, since I'm still using the "stable" version of modrana and it works fine. Besides, you can upgrade later on).
