Scan failed (Ferret pro)

Just got my Ferret Pro, after some struggle with the software (it works on my laptop, but not my desktop) I have manged to start it, but, I gett “Scan Failde” every time.
THe IR preview looks ok, I think, the same with the RGB-preview.
The objekt i all green in the main window, but when I press finish scan, it says that the scan failed.
