Same problem. Was just sending an email when it happened.
Now it is useless.

Hello everybody,

We’re sorry that you’re experiencing this issue. Could you please post a screenshot of the hard drive properties?

Thank you,

I fixed the problem by just deleting the mail.dat and index files. It is now downloading the emails from the server which will take a few hours. To delete every file and all the settings was not a solution.
