Sorry to hear that Lindsay .
My FP has not missed a beat since I swapped out the driver board .
I put the suspect driver board in my Tri Zone and it has been working fine too, but I've only played a few games on it since then , not enough to say that the suspect driver board is actually OK .
Having said all that , I would suggest trying another driver board as step 1, if you have one.
Cheers
Dave
