If youve tried CrystalControl and it doesnt work then your probably wired it up wrong.

Do you get a row of blocks when you give it power?
If you dont, then either your power supply or contrast setting is not right.

If thats ok, but the software wont work, then youve probably mss-matched the wires from the PC to the LCD somewhere.
