Cannot use my RMS

Why it does not working? It worked fine with the HD Version, with ES version too.
The DE only listed the RMSs in the Mod menu. When I want to choose any map from me in the map window the red button, back in the partie set up, is empty and the game is loading the coast map.

folder structure

Games/Age of Empires 2 DE/alot of numbers/mods/local/modname/resources/_common/random-map-scripts/

solved: game does not support Umlauts (ÄÖÜ)
