Migrating Feeds from blogger to wordpress

[nothing_for_nothing]

Hi,
I have recently switched from blogger to wordpress. In blogger, i used
feedburner and Original Feed URL is:

www.gaurishsharma.com/feeds/posts/default

In wordpress,
my URL should be:
www.gaurishsharma.com/feed/rss

I even validated it with feedvalidator.org -
http://feedvalidator.org/check.cgi?url=http%3a%2f%2fwww.gaurishsharma.com)

Now whenever i try to edit "Original Feed" url and enter above URL. i
get the MSG

"The URL does not appear to reference a valid XML file. We encountered
the following problem: Error on line 1: Open quote is expected for
attribute "{1}" associated with an element type "bgcolor"."

My feedburner URL is:
http://feeds2.feedburner.com/gslive


Please help!
