Hi...Yes,the message that came up said that there were NO restore points whatsoever...they have all gone...I eventually needed to go through the process of re-installing the disc and now it`s running as it should...but this has happened twice in the last couple of months...anti-virus turned off (by itself !),no restore points available and a change to the layout of the screen icons etc.
(edit)...I tried to restore several times but the message was the same...a red cross through an icon saying there are no restore points available...as if there never had been any at all !
After you have run the clean (Analyse) check on Options then cookies if you have any sites in there that you use regularly which require a password best keep them do that by highlighting them and send to the right hand list where they won't get removed.If you are not sure post back when you get to it. But do the scans first.
