[NTG-context] UTF-8 Problems with the minimals

Hi, after reinstalling the minimals (my HD crashed), I have got the following problem: texexec doesn't recognize UTF-8 any more :-(. I didn't change my tex-files and enabled UTF-8 with: \enableregime[utf-8] Surprisingly "context file.tex" works. I have no idea what is wrong with my MKII. Any suggestions? Thx. Greetings FloMo
