KSPI-E Won't Load

[Astronut33]

I am on 1.4.3 and downloaded KSPI-E, and what happens is in the loading screen as soon as it gets to the I-E parts KSP gets stuck and stops loading. It says "Loading PartRecipe for KSPIE Vasimir2" (Vasimir2 is just the first part it loads, I tried deleting it and the same thing happened to the next part." I am aware that I-E is only updated to 1.4.2, but when I tried to load it on 1.4.2 I had the exact same problem. The game doesn't freeze, as the loading pictures and flavor text still cycle. 

I have a decently hefty mod list, and as I feared, the issue is a mod incompatibility as far as I can tell. I put KSPIE into a clean clean game with no other mods (except it's dependencies of course) and it functioned fine. The game was even in 1.4.3, so that's not the problem. I have been unable to identify what mod is causing the problem, but any help would be much appreciated.
