LOL Death, we had a similar problem bringing the machine upstairs.
I also had a defective Monkey assembly and relay. My Winkie Guard switch was flopping around and needed adjustment. It also traps a ball behind it every once in a while. My Castle Doors also don't open properly and trap a ball in the popper stopping play. I have been told that some of this is a software issue.
I happy to say that Jack and Ken have been FANTASTIC about addressing my concerns. They respond to my emails within an hour and we have had emails back and forth well into the night on multiple occasions. They are truly interested in making sure that every machine they sell is working properly and are very receptive to my observations and suggestions even though I am a 'newbie' pinballer. The replacement hardware that I needed for the Monkey assembly was overnighted and Ken walked me through the simple installation.
I cannot say how happy I am that I bought a ECWOZLE and look forward to the promised software upgrades. It is a great game now and will only get better.
