Help! RSS feed is not working.

I recently moved my domain to a new host and since then, my rss feed will not work. I have read so many articles and have tried tirelessly to figure out what is wrong, but nothing is working and no one knows how to help me. I tried resyncing my feed through feedburner, but this is what it tell me:

There is an issue that must be addressed with your source feed for the feed “budgetwisehome.com”

Error getting URL: 404 – Not Found

I am at a loss and don’t know what else to do. I installed the feedburner configuration plugin and entered my feed URL:

http://feeds.feedburner.com/budgetwisehome

My original feed address is:

http://budgetwisehome.com/myfeed.xml

Is there anyone who can help me?! I am at a total loss. Thank you.
