http://stackoverflow.com/a/4251127: "You will see this message when you are in the 'Repository View' and you haven't set up version control. You can check this in the FILES tab/window. If you don't see it press F8 or select Window/Files. Switch from Repository view to Local View, Test Server, or Remote Server as appropriate."
Hope this helps,
The problem is reoccurring again and the solution that was successful before does not work. I don't get the repository message any longer but when offered to display the files on the remote server, nothing happens/gets displayed. I restarted DW, tested my servers connection and nothing changes. Any thoughts on this would be greatly appreciated.
I suggest starting a new discussion in the forum.
