I would contact them. Every time I have ordered something, and there was an issue they have always rushed me out 2 day replacement parts free of charge. Yes the potential of messing up one of my machines would make me mad, but in this case I don't think anything would of happened. I had my Pin-Bot main board repaired and the tech (VERY competent) simply plugged it into a Comet? and turned it on to see if it threw any errors.
