I believe the map is installed and activated correctly. It shows up as installed in the module manager. Selecting the map in the mission editor appears to use the newer map. At least London and Paris appear on the map in the editor so I assume this means all is good installation-wise.
I retried the Mosquito Rhubarb instant mission (after uninstalling and reinstalling the map) and now I think the correct version is loading. The textures look good and I can see London and Paris on the F10 map.
As you replicated, I continue to get crashes on the F-86 instant missions. I've attached the log files (Instant Mission, F-86, Normandy, Take Off)
I also tried an Instant mission using the MiG15bis. This time the mission loaded, and London (and perhaps Paris) appear on the F10 map. However, the map is frozen: I cannot move the map using either the middle or right mouse button, and cannot zoom in or out. So while it looks like the very northern part Paris appears on the map, I cannot move the map area shown to verify that Paris is really there. I've attached a screenshot.
