Well, if the TOR mod is the only addition, did you try removing that?
And indeed, galaxymap_p.gui is NOT modified by M4-78EP, it uses the vanilla version. The Coruscant mod however modifies it, poorly (using the same number for coruscant as M4-78, so only one can appear, Coruscant) which my compatibility patch fixes. However there's really no need for the file if you're not using Coruscant (and probably would do strange stuff if you try flying to a Coruscant planet you don't have).
