EasyBlog Control Panel is blank after upgrade

Last night we tried to upgrade to the latest 3.9 update for Easy Blog through the Easy Blog Control Panel on our Joomla site. It appears the update was not successful. Now when I try to access the Easy Blog Control Panel I get a blank page. Also, there is no Easy Blog content appearing on our website. Is there a way to reapply the latest 3.9 update? We were looking for an opportunity to upgrade to version 5.x. Would it be better to upgrade now or fix the issue first? Thanks!
