Thank you, that seems to do the trick.
So the package was shipped with V3.x while the registration stuff is for V2.x?
So much for reading the manual!
On 2nd hand, correct that, using V2.x doesn't work either.
Still failure and demo timeout.

I give up!
Perhaps there is a bug with the software? I'm now using v2.x and I still get some german error message.
Schreibfehler 42 bei block 14402, It's just a normal usb-disc working perfectly on my PC.
But the error log inside poseidon keeps telling me the demoversion times out. (Withint 1 minute??, isn't that a bit too fast anyway?)
