EasyBlog Theme Installation PHP Error

I purchased the EasyBlog extension for Joomla 2.5 today and I was able to successfully install it. I additionally purchased one of the supported templates that stackideas.com offers known as a wanderer. Upon uploading the tpl_wanderers_25.zip file to the template installation section of EasyBlog, I received the following PHP errors:

Fatal error: Class 'JArchive' not found in /home/private/public_html/http://www.example.com/administrator/components/com_easyblog/models/themes.php on line 109



Fatal error: Access to undeclared static property: JLoader::$classes in /home/private/public_html/http://www.example.com/libraries/loader.php on line 195

Thank you very much for your assistance with this error.
