language of side effects report

Hello together,

I do have a real stupid problem...

Working in Germany but in an english environment. WIN7 Installation, explorer... solution manager... everything is english. I am logged in SolMan in english, Marketplace english (prefered language english).. IE8 or Firefox are english..

What ever I try, requesting a side effect report in Maintenance optimizer, in marketplace .. for a single note or a complete support package stuck.. I ALLWAYS GET IT IN GERMAN ... I cant send this to american or finnish colleagues....

Any Idea what I could check? Before I loose my last black hair?

Manfred
