dropbox link to their site does not work in contextual menu nor in menu bar When right-clicking on a file in my dropbox folder in the finder, i get the regular window with (amongst others) the option to "view on Dropbox.com".  Clicking this link brings nothing.  Neither does clicking the world-icon in the menulet in the menu bar.
How can i 'repair' this little imperfection? 

(fyi: clicking the other link "Share Dropbox Link" actually does work, i have installed the newest dropbox.app on OSX 10.8.5)
Have you tried downloading the latest version of the Dropbox software (which can be found here: https://www.dropbox.com/install) and reinstalling on your Mac? 

To do this: 


Quit Dropbox from the menubar application
Download the software from the Dropbox website. 
Open the DMG file that gets downloaded 
Double-click the "Install Dropbox" icon in the DMG file 
Follow the instructions to reinstall Dropbox.
