After finishing one of the thieves guild quests Tonilia asked me if I wanted to upgrade part of my thieves guild armor set.The problem is,I accidentally sold all my armor to some random shop for gold.Now when I try to talk to her the "upgrade armor" chat option only appears-nothing else.Which means I can't even use her as a fence nor complete the "under new management" quest.To make things worse,I'm playing on a xbox so I can't use the pc console codes,and I've even forgotten the shop which I sold my armor to.

So is there anything I can do to recover the armor?Or am I seriously screwed and have to redo the entire thieves guild main questline all over again?

On a separate note,how can I unlock daedric/glass stuff besides smithing?

bump!
