RSS error message (parsing error)

Hi

My host’s server crashed some time ago and after they moved my content (http://www.madsenblog.dk/) to another server quite a few things have been messed up….

I get the following error message whenever i try to access my RSS feed (http://madsenblog.dk/?feed=rss2) :

XML Parsing Error: junk after document element
Location: http://madsenblog.dk/?feed=rss2
Line Number 338, Column 1:<div id=’error’>
^

Also…if you scroll down to the buttom of my blog an error message is displayed too:

WordPress database error: [Duplicate entry ‘628011’ for key 1]
INSERT INTO wp_ss_stats (remote_ip,country,language,domain,referer,resource,user_agent,platform,browser,version,dt) VALUES (‘217.157.173.103′,’DENMARK (DK)’,’en-us’,”,”,’/index.php’,’Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.9) Gecko/20061206 Firefox/1.5.0.9′,’Windows XP’,’Firefox’,’1.5.0.9′,1170681480)

I’m running WP 1.5.2….
