check out this link for some information on your error message. I had the same issue with my Pinbot and it was that my battery was not making contact.
Kick out arm in the eye sounds like it is simply gummed up. It is easy to remove just a couple of screws. Then completely disassemble clean it really good, I use a Harbor Freight Ultrasonic cleaner, but some simple green and then polish metal parts with some 0000 steel wool will do just fine. Then lube the metal parts that touch with Super Lube Synthetic Grease.
Here is what the response I got regarding lubrication.
As far as your flipper it may feel like nothing is binding but as a first step disassemble the flipper and check that the coil sleeve is okay and that the coil has not overheated and become distorted. Clean everything in the flipper if there is no damage. No lubrication on the flipper parts! Probably best just to rebuild the flippers.
Let us know how it goes.
