I've replied to this elsewhere, but let me reiterate here:

sean_lynch is not kidding about Dropbox's support staff. They are great, very helpful, and according to my colleague, are very serious about trying to restore everything. The issue he had was a software bug, and apparently some things are problematic to restore because of other technical reasons, but Dropbox has been very helpful.

And to make this clear - they were very helpful when this happened last week, before this thread - you don't need to write a blog post to get their help and attention.
