Yeah - it took me a couple of weeks to unify my different runtimes back to one. In fact i reinstalled all i wanted freshly into one Runtime - one week was simply to think about a good structure of that. Now all is working smoothly again, no search for textures, no missing items because the geometry is not found. Just straight forward working. But i know exactly how you feel - starting it was a nightmare.
