I´m feeling really stupid, but after I found that all my files was "zero bytes" and not having been active on Dropbox for a while, I tried to log in and accidentally (note to self: do not multi task when doing this!), I managed somehow to create a new account with my old email-address.
This account has none files obviously, and I´m desperate to reset it to my old one.
Is that possible?
NB. My hard drive folder, "Dropbox" does still show all the file names, but with "zero bytes" on them.
