Unable to start Dropbox due to permission errors I installed Dropbox 1.6.16 and am running OS 10.7.5 (Lion). I continue to get this message and don't know how to fix:

Couldn't start Dropbox
This is usually because of permissions error. Errors can also be caused by your home folder being stored on a network share.

I am the only person using this Mac and I don't have a network so this message doesn't make sense to me.
How can I get Dropbox to work for me?
Are you an administrator? If you are, try Chown and Chmod

Type the following into Terminal:

sudo chown -R yourUsername /Users/yourusername/Dropbox

sudo chmod -R 700 /Users/yourusername/Dropbox

If that doesn't work I'd run diskutil repairPermissions /

If those don't work, I would reinstall Dropbox.
