update logged me out and deleted my accounts

just did the update and it wiped out all my e-mails and now its asking to log back in with a new account. I have an office365 enterprise account and it wont let me log back in with Automatic Set-up, outlook or exchange…please help?

its asking for a password, put it in exactly and says’ "server says "(authenticationfailer) invalid user name or password

This also happened to my wife a few minutes ago she tried to put her details in again to “Register” the account but says this account exists and wants to know the number. HELP!

Hello Patrick,
have you perhaps accidentally skipped migration of your database when upgrading to version 7?
Try importing your data manually using the Menu>File>Import>Import from eM Client 6 option.
