I see errors in my xml feed but how to edit?

[Dan W]

I have a feed through Google Feedburner. 

There are three minor corrections I want to make. 

I can see the feed results via feed validator and know what lines I need to change. 

http://feedvalidator.org/check.cgi?url=http%3a%2f%2ffeeds.feedburner.com%2fEroticAwakening 

But what is the method or tool to edit the feed? 

Optimize/XML Source displays an error "FeedBurner was unable to process your feed. Please check the Troubleshootize - FeedMedic page for messages about possible problems with your original feed content."

Troubleshootize/Feedmedic and Podmetic display "Apparently, it's been quite healthy. Well done on your part!"

So, not clear what I need to do to edit the XML. Help?
