Problem with maps bought in the locus store
I have Locus pro 3.14.1 (German language) installed on a Samsung Galaxy S 5 mini with Android 4.4.2 From the Locus store I have downloaded two Swiss Topo maps and stored them locally. Everything was working well for some days. But now Locus shows an "Access denied" (Zugriff verweigert) message instead of the Swiss Topo maps. Other online maps and locally stored vector or raster maps are still working well. I have tried to reinstall the maps, but without any success ("problem with map".). The maps are stored on Locus/maps/swisstopo - hiking trails/mapname.sqlitedb and mapname.sqlitedb-journal. The maps are also listed in the map overview and they also show the correct region, which I can see, if I load an Openstreetmap, for exemple. But the Swiss Topo maps themselves (that means the display) are not shown.
Now I am unsure, wether I should buy more maps what I would do, because locus is a very good app. Thanks for your help.
