rss reader

Hi! I have som problems with my code... I'm trying to create a rss-reader which should parse the rss file and then show the result. But, there are som problems while tring to parse the file. I got an exception (XmlException) even before I start to parse the code(on the reader.MoveToContent();). With another rss-file the code makes thru that but gets stuck on another place, like at the description tag. So, my question is: What can I do with the code to make it work?!? My code can be found here: http://hejhej.org/Form1.zip and the rss-file can be found here: http://www.idg.se/tjanster/rss/rss.xml
