Problems while using Easyblog auto updater

I was using Easyblog's autoupdater and it got stuck at 10% of the updating process while updating the Foundry framework. Now when I try to access to the Joomla administration page I get a blank page.
Checking at the php error log I found out the following lines:

[Thu May 01 22:39:17 2014] [warn] mod_fcgid: stderr: PHP Fatal error:  require_once(): Failed opening required /public_html/media/foundry/3.1/joomla/framework.php' (include_path='.:/usr/local/php5/lib/php') in /public_html/components/com_easyblog/constants.php on line 225, referer: http://www.sitename.it/administrator/

I have a backup but it would take me a lot to enable it back. So I would like to know if there was a possibility to just exclude some file in order to have access to the administrator page and then doing an upgrade by installing the upgrade file.

Thanks
