I had been running Cubase 7.5 on OS X 10.8 without any problem. I upgraded to OS X 10.9 and when I tried to open Cubase, I received the following error message:
File Synsoacc.bundle could not be located in the Application Support Folder.
Cubase then quits. I used the eLicenser Control Center app to perform maintenance tasks without any problems. However, when I tried to run Cubase again, I got the same error.
