Internal Server Error

I upgraded my Joomla version recently and with the upgrade went easysocial. All other extensions are working fine but every bit of easysocial is throwing an internal server error (modules, etc), nothing easysocial is working. I have the latest version of joomla and also the latest easysocial version.

Any ideas on what files might need to be replaced?

I have tried unistalling/deleting and re-installing but I get a blank screen when I click on the social app links.

Also, when I unistall it retains the com_easysocial file in cpanel admin folder, and when I delete it I get a main site error that easysocial is not installed. I have tried deleting all 'social' associated tables in phpmyadmin but I still get the main site error that easysocial is not installed.
