Issue with wordpress and subdomain?

So I had to switch over our companies website to a new dedicated webserver (our main site is not wordpress) and then they informed me that they had a wordpress install on a subdomain of the site. So I took the subdomain folder, transfered it over, setup the subdomain on the new server and created / imported the wordpress database. This works and all the content is visible but there are 2 weird issues. On the new subdomain no images are being loaded, and more importantly the rss feed does not work. When I type in sub.example.com/feed it returns with page not found. Any ideas?
