I UPGRADED today to TB 78!

It MESSED UP my address books!

I LOST few address books (NOT converted!)

The ones converted have a .bak original MAB!

I always make backups, but was stupid enough not to make today!

I tried UPGRADING again using the MAB files / BAK files, at no avail... it's an ugly BUG :\

CAN I DOWNGRADE to 68 having ALL my profile info backup on 68 (using the mail data from 78?)

Here is what i did:

- Recovered a v68 backup (with NO MAIL folders!)

- Replaced the MAB files backups and MAIL folders from v78

The POP mail folders are ok, the IMAP gmail folders do not appear :\

I gave up!

I EXPORTED all the address books on v68 (CSV) UPGRADED to v78 DELETED all the address books from the UI RESTARTED DELETED few new empty address books from the UI (there was something really wrong after de update!) IMPORTED all the address books (CSV) All address books were created in order (SQL version)

NOTE: had to review ALL the mail RULES, because they were messed up (when the books were deleted)

A guess that's the best approach. I will keep the latest version.
