can't transmute khalim's will

[:1]I found the heart, brain, eye and flail, but when I put them in the cube and press transmute, nothing happens. HELP PLEASE:|||Hello, robjamjef. The correct thread location is here.|||Moved from Barbarian....|||Are all the items from the same difficulty level, the one you are in now?|||If you go into a lower difficulty level with them and then come back to the current difficulty, quest items sometimes seem to stop working. Once I had that with the Horadric Staff from act 2.
