Okay, thanks.
NOTE: I had to edit the XML in the file, because it says .... MozartS M2 EXPORT. Changed that by removing the EXPORT and now the MIR project loads fine.
However, there still is no sound. The meter on the top right does not move, though it works if I create a new project.
But I cannot guarantee that there is another flaw with my settings ...
EDIT: It says ... could not load VSL Compressor x64, VSL Equalizer x64
I'm running Cubase 6 x64.
Best,
Till
