I posted this in the "General" forum, but nobody could help there, so let's see if any of you technical people can help

SO I'm having a sinificant problem with my Vampiric Assassin Character, in that when I sleep to level up, I can fill in all my Stat Increase choices, however as soon as I click the "Finish" button, the game crashes.
Any Ideas why this might be/how to fix it?
For some background info, this is a relatively high level character (must be somewhere in the realms of level 25-35ish) and it has never happened before.
The only ideas/suggestions I have is that maybe it's caused by:
1) The fact that he is in the fullest stage of vampirism and maybe there is a bug where since some of my attributes are pushed up above 100 already by the "Vampirism" ability, the game has a problem with trying to increase them through a level up... but that doesn't seem like a very convincing explanation, since it's never happend before...
2) I have avoided levelling the character up for ages (so technically he is porbably "owed" like 5-10 levells up beofre all the "level up points" are used up) so that I can use all of my Trainer slots for each level... so maybe not levelling up for ages, therefore going way overdue a level up, then trying to level up, kind of 'overloads' the game or something...
3) Ulikely to be anything to do with it, but on that level, I used trainers to level up conjuration 5 times (essentially using up all trainer slots on conjuration).

But thats all I can come up with, any help would be MAJORLY appreciated, as I quite like this character, it would be a shame never to be able to level him up again...


EDIT:
Well, I tried wating a while and sleeping on a different bed in a different location.
I also fed so that I came back down to normal vampirism levels.
I also removed all enchanted items that could be boosting attributes and causing a problem.

Buuuut... still no dice.
Still having the same bug.

Look for settings in your oblivion.ini, in My Games\Oblivion, for tracklevelup or some such, make sure both settings are blank.

hmm... I searched, and found the thing you were talking about (somebody else mentioned it somewhere else on the forums)
but it was already blank, there was nothing I could delete... :/
any more ideas?

These two?

STrackLevelUpPath=
bTrackLevelUps=0

I think the second needs to be 0. (disabled)

If that doesn't help, have you turned off all the various "save on..." options?
