Hi,
I have no experience / knowledge about Arduino. To build an Arduino based weather station (http://www.meteocercal.info) I bought 2 Arduino Nano v3. Windows8 recognise the driver (CH340) and installed. Next I've installed Arduino 1.6.3. When I want to run the Arduino software just say "Loading configuration..." and close. I tried unistall and reinstall but nothing change.
I've tried 1.6.2, .1.6.0 and 1.5.8 versions but all of them never work. Only Arduino ERW105 works.
Any advice / hints will be appreciated.
