So here is my problem, oblivion works fine and has been for ages. But randomly its now crashing during the first loading screen but when I deactivate all my mods it gets past the loading screen onto the main menu and I can even play the tutorial. Ive tried everything, changing load order, rebuilding my patch a dozen times, deactivating recent mods, going through my list below and trying to use common sense to see anything that could cause this. None had any effect. I've been enjoying a full FCOM setup with no problems and this is the first time I've been completely confused about a problem, so I've gave the load order list below as that's probably the cause.

Any help would be greatly appreciated.

Could you post your load order from W.B. ?

This would be best in the mod section. I will ask a mod to move it.
