I thought these lines tell you something about the problem.
2007-11-02 11:09:31.328125 [ERROR][MPMain]: System.InvalidOperationException: StandardOut wurde nicht umgeleitet, oder der Prozess wurde noch nicht gestartet.
bei System.Diagnostics.Process.BeginOutputReadLine()
Indeed as it is the same error TLD already got - It must occur when a process that should have taken place did not work properly and therefore used StandardError instead of StandardOut.
Of course I could fix the error but I'd be happy if the cause of this would be fixed as well...
