Keep talking to MCE, write down names of who your talking to and try getting someone different each time. I have a job of 7 ibox cars, 500 fpm gearless torin machines. Once or twice a month we'd get a call in the morning a car was shut down. It would be in the overhead. I went through them cars with a fine tooth comb. Did everything imaginable. I had called MCE three or four times over the few months I was dealing with this and they had no answers at all. Finally talked to a 5th person at MCE and literally just says "oh yeah that's a known glitch we had. We'll just send you updated software" if only the first few folks woulda known that. We are all human and noone knows everything. Sometimes you just gotta talk to that one guy that actually knows something about your specific problem
