Hello Andreas,
no, it was really easy. You get an USB-Stick and just doubleklick on the software. Drag and drop the 3D File into the virtual printing room, press "generate autosupport" and then it will be sliced in the different, later printed layers. The software safes the "sliced" model on the USB-Stick. Put the Stick in the port of the printer, choose the desired model and press play. That's it. It really took me just half an hour to read the instructions and start printing.
Bye,
Manni
