How to get Rei's Minimap to work with TerrafirmaCraft and ExtraFirma?

(I'm using the 1.6.4 Forge) When Minecraft loads it says 7 mods loaded, the 3 Forge mods, 2 TerrafirmaCraft mods, the ExtraFirma mod, and the Rei's minimap mod. But when I load a world Java crashes.

You could try un-installing forge, and the re-installing it, or you may have the wrong file type of mod. Because some mods that have files that are'nt compatable with forge, and have a different download link that has the ones that are, also some mods just aren't compatible with eachother
