Can't get WordPress feed on my 360 Please Help!?

Hi!
I have 2 WordPress blogs and one I have on my 360 but the other one will not go. I keep being told that there is an error and they were unable to fetch the feeds and to check the URL. They are basically the same address:

http://URL.wordpress.com/feed/

I have been trying for almost a week can anyone please help me? I did read to look for the little orange button that is suppose to be located on my blog it isn’t there and I know the feed URL anyway, like I said the other one works just fine!

Any help would be greatly appreciated!
Thank you very much for the answer, I really appreciate it!
Hi again!

I just wanted you to know it’s tomorrow, my time, and unfortunately it did not change over, in fact it deleted the URL yesterday and before I turned off the computer I put it on again, but upon getting up I see that it has deleted again! But I really appreciate your answering me anyway!

I used:

http://thecashbox.wordpress.com/feed/

if you can you think of anything else that might work please post again!

Thanx again!
