Hi!
I have opened the file several times lately and no problems with missing recordings.
Even the colors for the tracks seems to stay correct and moving the recordings also works.
Noticed that Adobe put the updates of the new CC on the wrong harddrive and that my icon on the desktop linked to an older version of Audition (wich Adobe installed on the correct harddrive).
So when I clicked directly on the file it opened in the latest version of Audition.
Changed the location settings in Creative Cloud to the correct harddrive. Not shure why this has been changed but will check this more often in the future.
Regards, Orjan
