Milquetowst Tradeskill Window & Cookbook Crash

[mortis42]

Whenever I add a modified eq2ui_mainhud.xml file to my custom UI folder it causes my UI to not load properly... Black backgrounds to everything, the chat window is solid black and you can not see or type any text into it.
If I remove that file, everything works fine.

I've even made an empty folder and just added the eq2ui_mainhud.xml file modified to have an extra <include> and it did the same thing.
