Lost guild window scrollbar

[PigLickJF]

Hey, hopefully someone here can help me.

Some time back the scrollbar on my guild window quit working. I am using a custom guild window (Milquetowst's guild window), but since it broke I've tried reverting to the default UI, reinstalling Milque's, etc and no matter what I do the scrollbar doesn't work.

Any ideas on how I might be able to get my scrollbar back?
