SimpleMessageSystem error compiling

Can someone help me solve this problem?

When I’m compiling the SimpleMessageSystem_example1, it will appear this error message

“error: WProgram.h: No such file or directory”

That library has apparently not been updated to work with Arduino 1.0+.

The first step is to edit the library to use "Arduino.h" in place of "WProgram.h". In most cases that is the only change needed.
