[carpydylan]

Hello, can anyone help with this
i had a problem with avi video files so i decieded to do a system restore, after my system restore the problem still existed so i did another system restore back to the latest date.
since then i cant download anything from the internet, or save pictures or open internet explorer (on my user account, i managed to open internet explorer on another user account but couldnt download or save anything still)
i went back to system restore but i have no checkpoint dates there
what have i done? help, cheers

System Restore allows you to return to where you were when you started.

Or

Use your OS installation disk and the repair option.

Or
