Hi, N0440F290 is your initial cruise speed and altitude in ICAO standard notation. It is not included in the X-Plane .fms file and won’t cause this error.
I am not familiar with what the unable 5000 at [d-10] error means. I suspect you might have more luck asking about this in the X-Plane forums or in the support forum for the add-on you are using, as applicable.
