Problem solved. Apparently you need to make sure that your system allows downloads from 3rd party host.
For that you need to go to System Preferences, Security and activate the anywhere button.
Thanks for the help.
This worked for me too! Thanks Gordinsky!
I purchased several toontrack products recently. I installed, registered and authorized each one with success except for the Rock Solid pack.
Once I changed the security prefs the Rock Solid pack worked…go figure!
