Error -1073807246

Hi Everyone,

I am trying to connect the Arduino with LabVIEW LINX. However, when I setup the firmware through markethub > LINX > LINX firmware > Wizard and run an example to turn on inbuilt led on and off  I am getting following error mentioned below. I would appritiate any help on it. 

Kind regards

Error -1073807246 occurred at Property Node (arg 1) in VISA Configure Serial Port (Instr).vi->LMH-LINX.lvlib:Device.lvlib:Serial Open.vi->LMH-LINX.lvlib:Device.lvlib:Initialize Device.vi->LMH-LINX.lvlib:Initialize.vi->LMH-LINX.lvlib:Open Serial.vi->LINX - Blink (Simple).vi

VISA: (Hex 0xBFFF0072) The resource is valid, but VISA cannot currently access it.

This suggests to me that you the serial port is already open "somewhere else" when you run the example.  Do you have some kind of terminal session (including the VISA panel for that COM port in NI-MAX).  it can also happen if you abort a VI in LabVIEW so it doesn't get to close the serial port.  (Then you have to shut down LabVIEW and restart it.)
