I am running Vista x64, with KIS9 fully up to date. Turned it off last night and this morning turned it on and it had re set itself - it created a new desktop as if first installed. I had a few minutes to look at it and it appears that it has created a new user directory under C/Users. My old user with all my data is called andrew (it is still there), computer name is hal. New user, to which I think it loads, is andrew.hal. In control panel it still only shows my original user account andrew.
Can anyone help restore my old account without a reinstall. Suffice to say I wont be connecting to the interent until fixed.
