If the search is empty you can do CTRL+V at the home page and type in the two ICAO codes, Dept and Dest, with a space between. Your profile will be taken to the departure and the flight should then build to your destination.
But first always, always, test out a default scenario first - or much time will be lost attempting to circumvent problems elsewhere or other things confusing the issues. Also reinstalling can only reset the defaults and even then will pick up the current profile behaviour.
If you can get the flight built properly we can look at the jumps. The old version you have can be landed without much errors as the G force is off.
