Problem IMFD 5.5 with AMSO 1.19 problem

[MetalMania]

I'm trying to follow an AMSO/IMFD tutorial "From the Earth to the Moon", which I realize was written for older versions of Orbiter, AMSO, and IMFD than what I'm using but I would think that it's basically still valid (I hope).
I'm using Orbiter 2010. This is my first attempt at doing anything beyond watching a launch in AMSO as well as my first foray into IMFD. I'm trying to set up my TLI burn with IMFD. I have followed the instructions thus far and have the left IMFD in Course program, right IMFD in Map. Upon opening the right IMFD I set it to share from the first one by PG, ID = 0 as instructed. I followed the instructions to set the IMFD map to display the lunar intercept point, and proceeded with the next steps to set up the TLI burn. The tutorial says to go into Vel. Frame and set initial Lon, Lat and Rad to 4, 4, and 8M respectively. No problem there. Then set the Intercept GET to 75:54:28, and change "Realtime" to "Off-Axis" - all done without problem as well. I adjusted the TEj value to minimize the Enroute Tot.

Now here's where I'm stuck. It says to step up or down the Rad value to lower the PeA shown in the right (IMFD Map) MFD, and then do the same with the Lat value to adjust the EqI in the IMFD Map. No matter what I change those values to the IMFD Map values don't change. It's like maybe the 2nd IMFD window isn't getting the data from the Course program even though I set it to share. I don't know for sure if that's the problem but it's the best I can come up with not knowing anything about using IMFD other than what this tutorial is telling me. Is there a way to reset the 2nd IMFD to re-link with the other one? Am I missing something else, like a "send" command or an update command for the IMFD Map to reflect the changes made in the Course program?

There are a few possible causes that come to mind.

1: The Rad value needs to be rather large before it will show an effect. Try a starting value of 8M (use the <set> feature to type that in, and make sure the M is Upper Case). You've probably got this right, but I mention it because using the lower case m is a common mistake.

2: After setting the offset in Target Intercept, use the [MOD] button to return to the trajectory view and ensure that the word "Offset" (or Offset Enabled, can't remember) is flashing white. If not, hit the [TGT] button, select Moon to reset IMFD. You'll likely have to adjust the settings again.

3: In IMFD Map, [Plan] must be enabled. Your trajectory should be shown in blue, not green, and the word "Plan" should be shown in gray on the bottom of IMFD Map's display.

4: You will likely need to set a time limit in IMFD Map. Hit the [MOD] button (in IMFD Map) until the config page comes up, find the "Time Limit" line, and give it a value (in seconds) long enough to cover the trip - 750k should be more than enough. Essentially, the formula ((TIn - TEj) * 2 + 50k) works well, and should show the return as well as the trip out.

If none of this helps, attach the scenario to this thread. It should be at the point where you've set everything up as far as you can - and have the problem. I'm not online at home, it may well be a week before I can look at it, but I'll get back to you as time (and internet access) permits.

Here are a couple of Tutorials that may help you. The first link scroll to the bottom of the page and ck out the Simple Free Return Tutorial. This will explain alot. Then the next link is the entire step by step Apollo 11 mission. TheSnorkleMonkey has some fun stuff, take a look at all of his vids.
