I was able to fix my problem. I had only to download an older win file. In the newer windows programms it is missed so You have to download the file.
@Combat Wombat: You can change CMBB in CMAK and CMAK in CMBB maps. Further You can change scenario maps into OP-maps. For CMBO You must have version 1.12 to use the map converter.
CM Map Converter is a very useful tool for designers.
