update to joomla 1.5.26

I updated my site but when Easyblog is launched I get the following:
Warning: require_once(/home2/nick/public_html/media/foundry/2.1/joomla/bootstrap.php) [function.require-once]: failed to open stream: No such file or directory in /home2/nick/public_html/components/com_easyblog/helpers/helper.php on line 3480

Fatal error: require_once() [function.require]: Failed opening required '/home2/nick/public_html/media/foundry/2.1/joomla/bootstrap.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home2/nick/public_html/components/com_easyblog/helpers/helper.php on line 3480

Any ideas?
