I installed Logic Pro 9.1.8 from the App Store. After checking it out I selected the Download Additional Content menu option.
Everything downloaded and I entered my admin password. The installation appeared to be fine until it came to Jam Pack 1. It hung on that for well over an hour. Clearly nothing was happening.
I was able to quit the app normally. When I reopened it I was asked if I wanted to resume the download. I selected that but got the beach ball. Force quit and tried it a few times, same result each time.
Next time I selected 'cancel download'. Now the 'Download Additional Content…' menu option is greyed out. But I can't see the content. If I click on Loops everything is greyed out, as if nothing is installed.
I'm new to Logic and might be missing something daft, I don't know. Appreciate any help at all.
