Well,still found no answer.I'm running Concert Vault with the Internet Explorer now, although i didn't want to youse it anymore...But Firefox doesn't want to work with Flash Player 10, it seems.

@klamdup:Was that an answer?

Concerts won't play anymore - I suppose it's because the latest Flash Player 10 doesn't want to play the same stuff FP9 did before, but I can't switch back to the old 9-version.I'm using Firefox 3, latest version.Does anyone have a solution?Thanx.
