Calendar notification pop-up window shuts down eMClient

After other problems, it remains that if I want to keep eMClient working I cannot close the notification windows of reminder.
I tried to clear events and notifications from web gmail calendar, but the reminder is still there for a past event.
In GData.log, there is nothing.
eM Client (6.0.19179.0)
Windows: Microsoft Windows NT 6.1.7601 Service Pack 1, Framework: 2.0.50727.5472
The following error has occurred:
System.NullReferenceException: La référence d’objet n’est pas définie à une instance d’un objet.
à MailClient.Protocols.Gdata.GdataAccount.get_UserAddresses()
à MailClient.Schedule.ScheduleUtils.GetRoleForAccount(IScheduleObject scheduleObject, ISchedulingAccount schedulingAccount, IAttendee& matchedAttendee)

Thanks to the support of John Galis, the problem has been solved by restoring the database from a backup of previous date.
