Map Creator says 'Nothing to download'

Hey folks,

I am using Oruxmaps on my Motorola Defy Plus (Defy +) MB526 rooted with Cyanogen mod 10 Nightly. When I hit

'Maps'- Button
--> Map Creator
--> Confirm Instructions for Choosing 1st and 2nd corner for selection to be downloaded

I get the message 'nothing to download!'.

I have tried a bunch different online-maps ('Maps'- Button --> Switch map) but none of them worked yet

When I did the same procedure running my Defy + with Cyanogen mod 9 nightly everything went fine: I could chosse 1st and 2nd corner, choose zoom levels and download die map and use it offline.

Anyone knows What's wrong?
