I have dawngaurd on the X-box, and it allows you to become a werewolf again, even if you have already been cured of lycanthropy.

After being a vampire lord I chose to become a werewolf again (by asking one of the companions).

The process is instant, Vampirism is removed and Beast blood is added - yet my problem is that the ring of Hircine does not work. Instead of the extra power in the power sub-headings (titled "ring of Hircine") I have a message that says "map updated". The ring of hircine is recognised in my effects list but not in the powers list so therefore I cannot select it to receive multilpe transformations.

Is there any solution on the X-box that any knows of to assist me with this ?

I haven't seen/heard of a solution for the Xbox...

Only thing I could tell you would be to start from a previous save. Store the ring, then try to regain your beast blood and see if that works. If it doesn't you are SOL.

I have a minor bug I was a werewolf then I went to serana to become a vamp all went well but under the stats system log where it says days as a werewolf or vampire ect I'm getting both adding each day... So it's logging me as a vampire and werewolf everyday lol.. Don't get both powers though
