First of all, what W_clear was saying, is take the files from the fix and put them into the proper place in Environmental Mod 2.0. Don't JSGME both of them, makes for too much clutter.
Second of all, you might want to delete the fogdistances.cfg file from the mod, or replace it with the one from Env1.2.
If you do this, you should be ok(key word: should). I did this and have stopped getting the CTDs. However, I have only been testing in the Mediterranean. Hope this helps some people.
Edit: Shiplord, are you sure that you are using W_clear's latest ClimateZones.tga
