Ok, So I'm restarting my whole Mod. Wish me luck.
Wait. You don't need to go that far.
If all you changed was a few things and you think that's where the problems lie then do this. Go download http://skyrim.nexusmods.com/downloads/file.php?id=5064 then create a brand new esp. Then you open up the brand new esp in tesvsnip along with your old one and copy over the good records from the old esp into the new one (you can do that by cell, worldspace, NPC, misc item, etc). You don't need to redo everything.
Also, ya, don't give up. I cannot tell you how many times I have had a mod CTD at the starting screen or whatever on me. The thing I do is backup, backup, backup. Sometimes more than once in a day (that's when I'm trying something completely new and I have no idea what might happen because of it), but always at the beginning of every work session so I can go back to that if something unbelievably weird like you just had happen happens because weird inexplicable stuff like that just happens. Not often, but when it does it's tragic with no backup to go back to (which I've had happen too when I forgot to backup...urgh).
