I get the following error when switching from my old theme to my new one. It ONLY occurs on the homepage. Other pages aren't affected. Thoughts?

Warning: require(/home/dhadmin/public_html/modules/mod_k2_content/tmpl/slide_news/default.php) [function.require]: failed to open stream: No such file or directory in /home/dhadmin/public_html/modules/mod_k2_content/mod_k2_content.php on line 48

Fatal error: require() [function.require]: Failed opening required '/home/dhadmin/public_html/modules/mod_k2_content/tmpl/slide_news/default.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in/home/dhadmin/public_html/modules/mod_k2_content/mod_k2_content.php on line 48

Thoughts?

Just refreshed the page and now I'm getting this...
Fatal error: Class 'K2Table' not found in /home/dhadmin/public_html/administrator/components/com_k2/tables/k2category.php on line 13
