Hello,
I have been successfully running Mac 10.2.8 with Pro
Tools HD 6.1
Recently,I upgraded to Os X 10.3.9
Now my Pro Tools 6.1 does not work. Opening the app hangs system.
So, I tried to downgrade to 10.2.8, but did not
succeed. Put in a 10.2 OSx, but program did not allow me to downgrade.
I could not downgrade to 10.3.5 or any kind of downgrade.
Then I bought Pro Tools 6.7 software upgrade.
But each time I put the installation CD into the
CD-Rom,
nothing happens, the desktop shows no CD
icon. Go into Finder, there there is not CD-Rom icon.
What should I do?
thanks,
