Useless Aircraft beacuse it does not appear on the scheduled flights

I have scheduled my normally on my BAE ATP, but the routes it was scheduled is not showing. I’ve managed to cancel a flight that I knew that it has no return flight itself (CRK-BSO) and cancelled it on the last minute. And all of its flights were gone or distrupted. I’ve wasted 6 million on Aircrafts that does not fly at all. Help!
