Need gmail address associated with a feedburner account

[Dmitriy Likhten]

Hi, we have a FeedBurner account which hasn't been used in some time (http://feeds.feedburner.com/donorschoose) but we really don't have access to it. I think the associated google account no longer exists, and so I don't know how to actually gain access to this account again. The problem is it is still sending out emails and we need it to stop and potentially get the list of current subscribers.

If anyone can offer and help on the subject, it would be really appreciated.
