Hi Cedric,
first, just a note it is always better to put new items in a new thread. It helps us give more timely and efficient support.
To your issue. Could you please clarify ... are you having trouble connecting to your FET/board? Or are you having problems with your project? The message about device not recognized has nothing to do with the project. I would also strongly recommend using the latest version, v5.4. (i would install as a full fresh parallel installation with antivirus disabled)
Some common connection issues include
- dll version
- permissions
- antivirus
-drivers
Have you seen this wiki and checked the dll version?
