You could stretch your ground (pin 24) from pin 18 - 25,
I've heard that it makes it more reliable.
Use a test program (included in CAL)
If the test fail, the error lies (most likeley) in the computer
end, bad diodes, wires touching (use insulation tape) e.t.c
If you pass the test the error is in the calculator end.
I didn't quit get what you made the calc end out of,
but have you tried 2.5mm stereo socket + calc-calc cable?
