I already actually posted the fix for the bug to that quest here, first post concerning it on the site.

Your method requires Oblivion installed, his does not and it was the method I used too thanks )
When you first arrive in Solitude Roggvir is being executed for giving a "I'll let you go, just this once" pass on Ulfric Stormcloak. I talk to Roggvir's niece, one of the kids running around, she tells me her mother's sad ever since she stopped going to preach to Talos. I go talk to her mother, ask her why she stopped, she says she stopped because she doesn't have the Amulet of Talos, which is in Roggvir's corpse. I looted it, told her I have it, makes no difference, plus the dialogue option on which you say "I have it right here" is gone.
^ That I need help with.
