I am using the "hellow world" example provided. So coding is good to go.
one thing i have learnt from open source is nothing is ever good to go
a lot can change between the time the tutorial page was posted and the liquidcrystal library included with the Arduino IDE so it really might help if you posted your example code,
to be sure of compatability use the hello world example included in your version of IDE paying attention to this line LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
yours might be different, it represents lcd pins like this
LiquidCrystal lcd( RS, E, D4, D5, D6, D7);
It's all a learning curve, which is good, if everything worked first time round we'd never learn anything
