Hey guys,I play oblivion on the ps3,and I have a problem with my goty version...

That witch that does the cure,doesn't accept my blood grass ):

I'm play on the Usa goty version,and I'm a nord,it that matters.

It's a serious bug in your version of Oblivion. With the PS3 GoTY version that quest can't be completed. http://www.uesp.net/wiki/Oblivion:Vampire_Cure#Bugs
