Creation Kit crashes when opening .esp file

[circlejerk69]

I am trying to open a mod downloaded from the nexus to change a couple small things. I have done this before, and it still works with some other mods, but with a few specific mods, I have this issue.
Firstly, it says "Multiple Master files selected to load. Load operation aborted". I looked online and added 'bAllowMultipleMasterLoads=1' under the General tab in SkyrimEditor.ini, like many tutorials say to.
So now I can successfully start the loading process, but a few errors then come up, and I either say Retry or Yes to All, depending on what option it gives me. BUT IT NEVER FULLY LOADS, it always ends up popping up with that windows 7 "creation kit has stopped working and needs to close".
Any help?? I really want to edit this mod

I have exactly the same problem... Worst part, no one responds....

I gather it isn't something that can be edited via TESEdit? I've never used the CK to edit mods. Most I have done is make compatibility patches for my own loadouts. People generally don't respond if they can't be of any help, like this post, for instance. :P
