I recently downloaded new version of iTunes (11.3.1 (2) ). My OSX is version 10.9.4 running on iMac. When I go to iTunes and click on Add File To Library and then select file in music folder and click open, iTunes will not open and add file to library. I even tried several other files in my music folder that I have successfully added to iTunes previously and none are added. iTunes will not import any of them. Any suggestions?
