Subscribe Me-plugin & adding feeds to MSN

[Fonz]

I downloaded and installed the "Subscribe Me" plugin on www.pornomagnet.com
It shows all the buttons to add my feed to a personal Yahoo, Google, Msn, ... page correct but when clicking the MSN button the feed doesn't get added to my MSN page. When I try it on, let's say UW's Whoring Wives blog (http://www.whoringwives.com/tgp/porn-blogs/), it works just fine. The only thing sifferent I see is that the link to my feed looks likes this:

http://www.pornomagnet.com/feed/

and UW's link looks like this:

http://www.whoringwives.com/tgp/porn-blogs/?feed=rss2

Anyone knows how I can get my link to work without changing anything on the linking structure?

Thanks

EDIT: But then again, on ponygirl's blog (http://www.onepervertedchick.com/) the same linkingstructure as with pornomagnet is used...
