I'm using OBMM and already have tried redoing the archive invalidation. For some reason, after installing the darnified ui stuff and activating it through OBMM, the textures in-game all reverted back to default. Anybody know how to fix this?

Edit: If it makes a difference, I'm running the steam version of oblivion... Also, when I DEactivate the darnified ui the qtp still isn't working.

Anyone?

Sounds like archive invalidation. Set to BSA redirection and check the box to autoupdate on exit. You need to use OBMM everytime then after installing any mods so it gets updated. That is my best guess based on similar experience. From everything you said that has to be it.

BSA redirection doesn't need to updated, which is one of the things that makes it preferable to other options. Once you have it going you don't have to do anything. But, yes, set to BSA redirection via OBMM, UOP or the standalone version.
