RSS Feed Not Working

I just recently switched servers and since then, my RSS Feed will not update. It just shows my old posts and does not update to display my newer ones.

My feed: http://fresh-season.com/feed/ – Here, you will see all of my posts (new and old), but once you subscribe, you will only get the older ones.

I tried the Feed Validator (http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Ffresh-season.com%2Ffeed%2F) and it said: This feed does not validate.
Server returned HTTP Error 404: Not Found

I’ve looked around on WordPress.org and other sites ALL DAY to try and figure this out but I can’t 🙁 I would greatly appreciate it if someone could help me!

Thank you!
