Hi Linda,
That's the first time I've heard of that error message - perhaps it's based on the level of your account with Dropbox? I know a number of users in this forum have shared that they use dropbox regularly to share their files.
I still haven't maxed out my Dropbox capacity, the error message (error 429) said it was due to the amount of traffic to my files. I have the basic service, but when I Googled the error message, some people who paid for the upgrade had the same issue.
My files are back online now, but if I get a bunch of views tomorrow, it could be down again.
