Mac OSX El Capitan 10.11.5

I cannot get the app to open. After I get to the folder, and click on the Mp3tag.app, I get a screen: Verifying "Mp3tag.app" and it stops about 1/3 of the way down the bar, and then nothing else happens.

I have my system preferences under Security and Privacy (that is the same icon on the above screen), checked to allow apps downloaded from anywhere, firevault turned off.

What should I do??

Thanks!!

Have you seen this thread: /t/18257/1 ?

Thanks for the link to the new tag mac OS app, however the link is broken, I get page 404. I did not update my OS to Sierra, am still 10.11.5, but am willing to try the new app. I have my security to all apps from anywhere already, and since I can't get the app to work, even from the application folder, lets try the new build.

Thanks a bunch!

That is strange as I tried it just a minute ago and it leads to exactly that thread from a couple of days ago: /t/18257/1
