Files to ignore on the updater

[Mr_Mc_Me]

I use a custom tradeskill window that has always worked with Profit UI. I use the updater which I love. When I go to update my files, I click on the tradeskill window's .xml file as one to ignore so it doesn't overwrite my custom file. But, it doesn't ignore it. It overwrites it everytime. Is there something I'm doing wrong, or is this feature not working properly?
Thanks!

PS. LOOOVE the new 4.0 version - I want the market window back though! When I try to install the side-by-side one from the old version, it messes up the entire UI! Hope a fix is on its way..
