Cant mount DMG
I use MacOSX 10.8.3. Today I download PGP Desktop Email 10.3 and when I try to open DMG file, I see this message: 'no mountable file system'
I try earlier downloaded PGP Desktop Email 10.2 distributives (was installed a year ago) and receive same message.
All other distributives (from Adobe, Google etc) opens normally.
