Feedvalidator

I have a problem to which I have no technology skills to solve it with. I am new to blogging, and I burn my feed using feedburner(I hope i have the right wording).
I registered to the Kenya Blogs Webring,(KBW) however my feed could not be validated by the KBW feedvalidator, everytime I pasted it straight from the feedburner to the KBW feedvalidator, could anyone please help, if they have an idea on how I should go about solving this problem.
The significance of this is, as long as the KBW feedvalidator cannot validate my feedaddress, my blog cannot be listed in the Kenya Blogs sidebar, am so lay in this but if anyone understand whatever am mubling about, please help, I fall short of solving this, even though I have tried.
