Site giving me a 500 error after renewing hosting

Permalink
www.emacpr.com is unavailable, it says I have the latest version of Concrete5 when I go to index.php/tools/upgrade/. It seems to have broken on the day it was renewed, Apr 19, if you check the cache on Google the last time it was cached was Apr 18th.
When I check the errorlog, it says:

[19-Apr-2010 20:44:36] PHP Fatal error: Call to undefined method SimplePie_Item::get_summary() in /home2/emacprco/public_html/packages/ticker/blocks/rss_displayer/templates/ticker/view.php on line 27

however that .php file doesn't seem to exist. I am not fluent in php, in fact I didn't build this particular website. The web developer who did it quit the company shortly before I came in.

Download the ticker package and remove it from server. Then try to install the package again from your project page.
