Due to recent changes made in Dropbox paid accounts*, users have reported files defaulting to Online Only, making them unusable in Engine DJ. 

Dropbox users on Mac will be notified when the change occurs via an on-screen warning. See below. 

To correct this, please make sure your Engine Library folder is made available offline.

For more information on how to make Dropbox files available offline please click here. 

*Users with free Dropbox accounts are not affected.
