Comment (by togmission):

 "Unexpected response from the server. The file may have been uploaded
 successfully. Check in the Media Library or reload the page."\

 I was having the same error message with mp3 with the size of 10.6mb
 (lesser than that got uploaded). **Finally deactivating WP Security Plugin
 solved the issue.** (I am using All in One WP Security)

 Give a try!
