I have seen loads of people having these kinds of issues with Dropbox since 3 years ago.
Unfortunately this issue remained unsolved by dropbox until today.
What happened was I joined our company Dropbox team a few months ago. Now they are changing the subscription, and one of my colleagues wanted to remove me from the Team.
In doing so, she deleted my account due to misunderstanding of the website wordings.
On my computer, my downloads, desktop, documents files are gone.
I tried restoring my files from Apple time machine but failed. It says the upper files path does not exist.
Some traces deleting the folder somehow broke the path to the folders.
I am in desperate need of recovering my account.
