I'm having the same problem and have no idea what the solution was here.
Using the example code it just produces
Int. Temp =
T/C Problem
With the second line flashing.
I worked the hello world code and the lcd works.
I worked the serialthermocouple code and that works when watching the serial monitor of the temperature.
But when I use the lcdthermocouple code like the original poster I get the same error.
