When I make a backup from the principal identity (including contacts and parameters and rules), I disconnect my Transcend 320GB and lose all contacts and parameters. Only mails remain. It's very fastidious. What should I do?
I recommend re-installing the software using the new version because this could be a bug in the application. The software was downloaded on my computer and it worked normally. No files were deleted without my permission. Re-install the software but use the default settings. Additionally, take a look at the SYNC operation. Turn it off while the backup process is going.
