Default [Q] Install another launcher on Dirty Unicorns 6.0

I'm using du_skyrocket_20140308-0422, I love it and have no plans to change any time soon but every time I try to switch to next launcher 3d it keeps giving me a notification saying "unexpected error...." "please select this to help us fix the problem". I was just wondering if this is due to the rom or the launcher. It is the full (paid) version and I've never had a problem with it before, maybe it has to do with the file system/type.
Would there be anything I can do for a work-around, aside from changing to another rom?
