Hi... just joined the forum today but have been using Orbiter for the last three weeks and am addicted (spending way too much time with it :)).

I've run into an issue using IMFD 5.1m with Jarmo Nikkanen's tutorial Moon2Earth and was hoping for some guidance or suggestions. This tutorial explains how to use IMFD to launch from the moon and return back to earth via the following menu options: Planet Approach > Surface Launch > Orbit-Eject.

I set up everything exactly as instructed, launch into orbit and then under the Orbit Ejection and Transfer section of the tutorial, attempt to change "Realtime" to "Pro-grade". However, the program will not provide the "Pro-grade" option; it only shows "Realtime" and "Off-axis" as available!

I verify that 'EIn' is less than 2.00 degrees. In fact, it's usually less than 0.02 degrees because I'll perform a plane-change burn at one of the nodes.

I've triple-checked all other settings, verified that all screen shots match, and have tried reinstalling Orbiter in a new directory and then running just the IMFD 5.1 module, all with the same results!

Can anyone suggest a course of action or clue me into what I may be doing wrong?

Thanks for help and this great forum community.

Off-Axis mode replaced prograde mode on the newer versions of IMFD. See the IMFD manual.
 
Well, there you go... best I get some new ink and print the IMFD manual.

Thanks for the help and prompt reply Chuck.
