zoomkat:
Is it possible that the Ethernet or SPI Library on my PC is outdated ? If so, is there a link where I can download the latest versions of Ethernet and SPI ?
When I download a new IDE version, I make a new folder for it so there is no mixing of the librarys (I make seperate shortcuts to the arduino.exe files so I have all the old IDEs available as needed). You might reload the 1.0 IDE to make sure you have the latest files.
Thanks zoomkat. I will download and re-install the IDE.
