Some of you might have received this message when running the latest Boxifier (1.5.2).
Dropbox 8.3.16 is an experimental early release and experimental releases are not supported.
We recommend that you always run the current stable version of Dropbox.
The current stable build of Dropbox is 7.4.30 ( https://www.dropbox.com/release_notes ) and you can get it from here: Download & Install - Dropbox
We also recommend going into your account settings on Dropbox.com and opt-out being included on early releases of Dropbox.
You can go to www.dropbox.com/account and scroll down where you see the Dropbox settings section:

Then you can uncheck “Include me on early releases”.
