SimpleXML error

Hi All,

I’m currently running WordPress 3.3.2 and I’m using a theme called Callisto. However, for the past week, everytime I log-in to my dashboard, I get a long string of errors related to simple xml. One string would go like this:

Warning: simplexml_load_string() [function.simplexml-load-string]: Entity: line 10: parser error : error parsing attribute name in /home/petathea/public_html/wp-content/themes/Callisto_Theme/functions.php on line 361

When I was reviewing the location of the error specified, I noticed that line 361 contains a code where the theme maker allows the theme to check his/her site for xml updates to the theme. When I checked the url given there (http://icarusindustries.com/theme-changelogs/callisto/notifier.xml), it looks like the developer of the theme closed up shop and now I’m left with a dashboard full of errors. I tried removing the code that updates the theme but it creates more errors. Hope someone can help me.
