Load Content Not working

Hi so i installed Solr and then the Advanced Search by My Solr Server plugin. Then i checked to make sure that the Solr instance was running and everything checks out including the “check solr instance settings” but when i try to load content it just seems to keep spinning endlessly. I have a lot of posts but its been hours and no move in the amount that has been loaded. any ideas?
