I'm gonna make this simple for you guys.
If you're using a custom stage mod, like Unleashed PC Project, disable BB and BB2 by renaming the folders.
Only use the ENBSeries Ambient Occlusion if you are using an ATI chipset, otherwise use the included nVidia Inspector profile.Disable ENB AO in enbseries.ini.

The stuff that is not in a folder goes in the root of your generations install. Inspector can go wherever the hell you want, it's not a part of the mod.
