I've never used open freely, but from looking at the screen capture it looks like O.F. just associated it's self with the plugins in Mixcraft. Maybe it thinks it can use the Mixcraft plugs within O.F. because of file type association? I know a different video program this is true of. Of course I never tried such a thing so... Anyway, I would think it would be safe to uninstall O.F. If you never moved any of your plugins they should remain as they've been. Hope this helps.
