First up, thanks for the support.
Anyway, I would suggest uninstalling what you have, then installing the latest nightly build (
http://wowuides.wowinterface.com/nb/...1.0.200.4f.msi). Now you do not need the files from the custom interface kit, so go to your Interface directory and delete everything
except the Addons directory. Run it and see if its any better (it works fine for me with that code).
