Mac 5.2.1 not working , what could be wrong?

Problem Description: I installed MAC 5.2.1 from Subsonic.org website. Error Message I get after having installed and launching application You can’t open the application “Subsonic.app” because it may be damaged or incomplete.
Troubleshooting Steps: Last time I tried from Subsonic I got same error. I then downloaded an older version from another website http://sourceforge.net/projects/subsonic/ That worked!
Playback Application and version: LocalServer
Subsonic Version: (copy/paste from the "About" screen in the Subsonic Web Interface)
Server Version: (copy/paste from the "About" screen in the Subsonic Web Interface)
Hardware Platform: Mac Yosemite
Anyone experiencing similar troubles on Yosemite?
Cheers,
ZF
