No Relays were harmed in the running of this code, because those are solenoids.
What kind of solenoid are you using?
The code assumes it is a single solenoid (one physical set of wires).
the solenoids we've goten in the kit the past couple of years have been double solenoids (two sets of physical wires).
Post your Begin so we can check that out too.
P.S. to your edit.
A -44027 error is "FRC: The DIO channel has already been allocated."
That means you've specified the same DIO more than once in Begin.vi. Probably the default DIO 1 came up twice.
You can get info on the mysterious error numbers by going to
Help->Explain Error... and typing in the error number (remember to include the negative sign if appropriate).
