Hi I have a problem with converting downloaded maps from "map this" to a file for the ipod touch app "maps ofline" by nam. Once it worked out with the converter that one finds in the "map this " application but now i downloaded a bigger map and the converting progress breaks up at like 4 percent and a warning popps up which says. "Error:database file is locked" or somethign like that. Do u know what i can do. I would really appreciate any help u give me cause i think this is one of the best apps for a jailbroken ipod touch.
