GM:S 1.4 AssetCompiler Error (I'm so frustrated)

So I've been doing a new prototype every day with GMS 1.4 up until a few days ago when GMS started flipping out. First, it would crash on run, then it wouldn't run at all but I've fixed one problem after another. I finally got it working for about 24 hours before I came across this error. I am totally stumped and furious. This error has halted all game dev progress. I am starting to take game development seriously and desperately need a fix for this. Thank you.
