Hello, The above described configuration worked well under Win 7. after upgrading to windows 10 with a clean install and installation of the latest versions of NVDA and BRLTTY i get an error message when selecting BRLTTY from the braille dialogbox in NVDA. It seems that the communication between BRLTTY and the CombiBraille works because i get the usual message on the braille when the BRLTTY service is loaded. Is there anything i can do to get braille working again? Many thanks! Rene
