Hi Tobiaus,
Maybe you don't care about the following if you've already gone to 2.0 ... . I'm not exactly sure what happened when you tried to install flash 10, but if your browser crashed while you were doing the copy, perhaps that had something to do with it -> I really didn't try to do any special config or anything. If the browser is recognizing it, then it should show up when you enter in "about:plugins" as a URL.
