Thomas, an alternative viewpoint: how many members in the German Fox User Group which apparently owns FoxRockx? Maybe somebody in the user group should approach the other members/shareholders to ask if they're willing to invest another few Euros each to make this problem go away.
Just curious... do you know whether the requested figure of 1500 Euros has some sort of significance?
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
