There was an error at installing cd Audio Content 1 and did not notice. Everything else, Audio Content 2 and Jam Packs, installed properly but how can I add the Audio Content 1 CD after everything has been installed?
If you have an answer please be very specific with the instructions. Please help me
MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)
You could re-run the installer, or, once you have updated to Logic 9.1.8 you could use the "Download Additional Content" function in the Logic Pro menu. It will tell you what is installed and what is incomplete.
