Over the past week I am unable to share (invite via email) to anyone - says reached 24 hour limit - which is impossible as I've shared no link with anyone in 24 hours. Waited few days tried again and same error message. If I can't share any folders via drop box then it's useless to me. Can someone drom Drop Box fix this for me, I've tried to sent to just one person and it does not work? And I waited several days well over the 24hour limit, not that I sent the file to anyone previously.
