Query: Lid doesn't fit right...

I am not dissapointed with the ice-cream, but after putting the lid together and fastening in the motor arm it doesn't want to stay in. It keeps popping up and therefore the machine wants to stop..I put a small book on top of the motor arm then it stayed down long enough to churn, but in the process started smoking a little..I finally cut it off..afraid to use it until someone can tell me why the motor arm isn't staying down in place.
