EasySocial 2.0 backend failed installation

Hi! I tried updating EasySocial to EasySocial 2.0 but when the installation was complete the back end didn't seem to quite load right and I got a message saying that I still have an old version of EasySocial and that I need to update... That aside the front end seemed to work right. Am I somehow an exception? I tried again and again, but I still got the same message. Aside from that can someone please point me to a source on what exactly is new in EasySocial 2.0?
Thanks!
