Aaron, you seem to be having lots of issues with config files that I haven't seen..
If you have a spare moment on your server, you should backup your garrysmod/data/ulx and garrysmod/data/ULib folders, then delete the originals (and make sure the addons/ulx/data/ulx and addons/ulib/data/ulib folders have NOT been modified from the SVN versions).
With XGUI, we're trying to make it as easy as possible to edit configurations without having to manually edit files-- because tiny errors with manual edits can cause a whole slew of random problems that can be hard to solve.
Try the above and recreate your configs as much as you can in the game itself, and let me know how that turns out.
