Hot to block update?- Emclient8 multiple errors

Update EmClient from version 7 to version 8 destroy my old configuration and crashed several times with multiple errors.
I reinstalled version 7 but I discovered that version 8 changed the format of the mailbox, so I had a nightmare to recover my mails. I spent a day in solving that. Total disaster!. Happy Saturday.
I dont want nothing to know with the new update. I would like to know how to block update site via redirecting ip number in host or other way to block the update window. I really do not understand how EmClient launch a new update with the minimum compatibility between versions and with so many problems.
Yes. I am not happy with that.
