Ah, right, sorry.
Look how it goes: basically, Thorgrim's editor was old and unsupported when Warband came out, circa 2010-2011. Because of how it was written, it didn't really like Warband too much, so I made this little thing which uses 1.011 as a "working horse" of sorts to circumvent these errors. At that point, I think, it wasn't too uncommon for people to have both installed at the same time (I certainly did, and I actually ran two Warband installs at some point), so I didn't think this would be too much of an issue.
Looking at it now, four or five years down the line, this is like applying a band-aid to a (moderately large) knife wound. Technically helps, but probably not the best solution all around.
At any rate, PLEASE DO NOT USE THIS APPLICATION; in fact, I'll go ahead and add this to the first post. It's old, it's pretty ****e, my total development time on it was probably two hours or whatever, and it's not what you need.
