I am using a North American xbox 360 elite (black with 120 gb HD)
I completed ED and recently bought DKS. Made a full install of FoV and am unable to access my saved characters from ED.
I removed the FoV disc (DKS)and put my ED disc in and my old saves were present. I then replayed the final battle in order to get a fresh save, which I have a manual save and an auto save.
I put the DKS disc back in and still cannot access my old ED saves in either FoV or the included copy of ED.
Saves of new characters all seem to be working fine with DKS.
I tried to recreate my character as best I could, but he has lower stats due to not getting points for skill books etc. That isnt really a big issue for me though.
My main concern is that the Battle tower now is now loaded with the rejects I had killed on the island. I miss Igor, the enchanting couple, and the alchemist that isnt a weasel. Please help!

AFAIK all patches are up to date via xbox live.
