I just reinstalled Oblivion as well as some old mods I used to play on. I didn't think any of these were known to be incompatible and I have experience with installing mods.
Here is the load order.

I use Oblivion Mod Manager, OBSE, BOSS, and Wyre Bash and consider myself at least slightly competent with modding, but I've never had this problem before.
Thanks!
