Sorry for my English. Please help me.
I'll take a look at that. I don't know German, but I've seen that message in my PC many times (although none of them was with SDSME). Thanks for reporting it.
The language of the program is determined by the language the PC is set to. If you have your PC in English, SDSME will appear in English, and the same will happen with Spanish and Italian. Other languages aren't available yet.
