Reroot with razrs edge and you'll be all set.
It won't harm your other ROMs if that's what your thinking. What you can try is to switch over to eclipse and see if you have root on that ROM. If you do than phone is still rooted and your problem is the blurry build you have there. If you want to run blurry I would stick with version 3.8 until eyedea and Timmy figure out what is going on with the latest blurry builds.
