Aliens & UFOs Forum - RSS feed messed up

Hope this is the right forum, if not please let me know. There seems to be some problem with the Alien & UFO's forum RSS feed... if I load it in IE7 it gives me:

Internet Explorer cannot display this feed

This feed contains code errors.
Go back to the previous page.

More information

Whitespace is not allowed at this location.
Line: 4 Character: 49

AboveTopSecret.com New Topics In Aliens & UFOs

Firefox gives me this:

XML Parsing Error: not well-formed
Location: feeds.abovetopsecret.com...
Line Number 4, Column 49:AboveTopSecret.com New Topics In Aliens & UFOs
------------------------------------------------^

Some RSS feed readers are able to pull the info, most not... and it's been like this for as long as I can remember.

Is there someone that could fix this please?, it would be much appreciated.

Thanks
