Can't download a single file from my Mac.

Could you try right clicking the file first and choose 'Available offline' to see if this downloads the file?

And when I double click on the file itself I get this error message. And YES Im online and connecting to every single other thing I ask for.

Also icons are grey in file list 

Heres a screen shot. when I click on thr download icon nothing happens.   It doesnt even spin or change color.  

And there is no status button ANYWHERE for dropbox on the desktop other than above in system tray 

Do the files in Finder have any sync icons on them? When you click the icon in the menu bar, what is the current status of the Dropbox desktop application on the bottom left?

I am signed into the correct account and all my files are in my dropbox folder in my finder. I simply cannot DOWLOAD them from the dropbox server (where you store them)   I click on ANY file and nothing happens. 

This is why I asked if I shold delete the folder and start over. I reinstalled tje app WitHOUT deleting the file folder of my dropbox files on the macbook.

Hi rebel93465, since you mentioned that the screenshots shows that it's an unlinked Dropbox folder, are you certain that the Dropbox desktop application is signed into the correct account as on the Dropbox site?

Are you looking at the correct Dropbox folder on your device? Could you use these steps to locate it?

The dropbox server  where you store files.... vs local files 

Can you please first clarify what you mean by "server", rebel93465?

Wondering if I should be sure all files are on server, delete Dropbox folder and app and reinstall?   I deleted the app and reinstalled but not the DB folder in Finder..   Im a tech consultant FYI - its acting like an extension is missing?    I thought reinstalling the app would fix it but it didnt.  So wipe it clean and start over (meaning dropbox clean not whole mac)
