If that's really your load order, then no wonder you're having problems
Anyway I really recommend you use BOSS to sort that properly. I suspect that will fix your problem. I also recommend you install Wrye Bash and create a Bash patch. That's an awfully large load order to not have a Bash patch. It will make your mods run together better.
So here's http://www.gamesas.com/index.php?/topic/1280759-rel-boss-better-oblivion-sorting-software/ - use that on your load order first.
Then install http://tesnexus.com/downloads/file.php?id=22368. Just grab the 295-2 installer.
Then follow the http://www.tesnexus.com/downloads/file.php?id=35230 on how to create a bash patch.
That might seem intimidating, but it's not really that bad. And you should find things work better when you're done.
