mail problem

I have update the patch for acer communication sute, than the mail can not retrieve mail anymore! before the live update, i installed wine and picasa via yum, and now when i start live update and click history, a message appear "Internal Error: The update list can not be retrieved", what's wrong, did i mess up anything?

 

I think I know what is the problem! I have downloaded a installer from Acer's FTP, printer.sh, and I ran it with "bash printer.sh", but its info is not listed in the "update_info" folder, so online update can't find it, I just create a file called printer.sh.xml, it works again, I don't know what going on with Mail, but it works again!
