fm:
Can you put a snippet of the error you are getting?
The library in independent of the version you are using.
Do you have any other LiquidCrystal library other than the New LiquidCrystal installed in your Arduino library folder?
I tried it in Windows and received the same error as before. I am not sure what is going on. It does not seem to be operating system related and I download new version of both Arduino 1.01 and the LiquidCrystal library.
