Vampire Cure Quest, HELP WITH A BUG!!! Options

[HyPN0]

OK,I DECIDED TO GET RID OF VAMPIRISM,SO VISITED THE WICH.I GAVE HER EVERYTHING SHE NEEDED.......BUT........

WHEN I ASK HER ABOUT MY CURE........


Nothing! The wich has everything she needs,and yet she doesn't want to give me the potion! First i thought,maybe i should raise her disposition?I did that (to a 100) and nothing happend.

Then i though:Maybe i should come by day time,instead of night time?
No result.She refuses to give me the potion.

My only guess is that this is a bug.
If someone knows where can i download the fix:please tell me.
If someone knows the console command to get the quest to the next level (i don't want to cheat,but this is for fixing purposes) please tell me.I don't want to finish the quest with a console command,just to trigger her to do what she was suposed to do in the first place.

I don't really need the vamp potion.I'm ok with being a vamp with level 1,it's almost the same as if i'm not a vamp.But i do want the cure for counts wife.I wonder what is the reward for that (DON'T TELL ME!!!).

You need to wait 24 hours so that she can concoct the potion.
