I sent a copy of the database, however I put here the message you send to epimsuport unanswered ...
At the forum I am not alone, but two friends, my cousin and my brother all have the same problem.
I'm Javier Antonio Nisa Avila - Essential PIM PRO portable 4.52 - windows 7
The bug that is described here viewtopic.php?f=1&t=11370
is not fixed in 4.52
I sent a copy of my database in the following link to download http://www.box.com/s/gdesbvj9xhfdbd7l5r9m
the password of database are "EDITED"
In folder Inbox are two emails with the title "Su factura 605721866 del 01.05.2011" of December 25. The two are equal and should have the same attachment. But one has no attachment.
That is because one has received no activated message rules, and another message the rules enabled.
The rules of message failures are those that are can be found in Tools -> Message Rules. The rules that cause the failure to activate are "Vida Laboral Sevilla 3" and "UGT"
It is a mistake that I think is serious. If you need anything else please ask me
I can confirm that you have received this message.
