I can't open my files on my Mac

same issue on my new mac. everytime I try opening one of my dropbox files it says it cannot access the file or its not available. 

I did all those things and spend a lot of time with tech support. The right-click to get a dropbox link from finder is selective. Some files it works and others it doesn't. I give up.

I have Dropbox downloaded on my Mac, but I'm running into a issue i've never seen before. When i go to Finder > Dropbox > and open a file, i get the error message "could not be opened resource deadlock avoided." What is the solution to fix this? 

Hey ai2323, thanks for bringing this to our attention.

Are all your Dropbox files giving you this error message?

Does the error come up when you try to open files that are set to 'online-only' or 'available offline'?

And what's the sync status and version of the Dropbox app?

You can hover over the Dropbox icon in your menu bar to see this info.

Thanks in advance!
