    Have you got a System Restore point/backup etc. etc. you can roll back to?
    Can you get into Safe Mode?
    If you say no to the first and yes to the second, do a search through the WinSXS folders ( your Sytems backup), also the AMD (?) folders if you are running 64bit. Copy the files from there and replace your dA modded files with the correct ones. You could even run sfc /scannow but that will replace all your modded files.

    Why were you trying to replace the authui.dll file? (just curious!)

    And if the second doesn't work, boot into a Linux live cd with a copy of the right dll on a flash drive. Then copy it into the correct folder.

    I dont think I have got a Restore point, and Safe Mode is doing the same.

    Biggles option is looking favourable at the moment then!

    If you've got the disk, a repair install should do the trick. I'll bow to others superior knowledge on that department though, as, touch wood (taps head) I've never had to do one. Yet!!

    I dont have a Windows 7 disk, Windows just came with my HP Laptop. I have a idea if I install Windows XP could I go to my Windows 7 files and change it there?

    Not the best choice. Installing xp after 7 is always very tricky and windows will most likely complain about the security issues of you changing parts it doesn't want you to.

    For the Linux option, just google 'Puppy Linux'. On the official looking site, find the (it's less than 200MB) latest iso, download it and burn it to a blank cd. Copy the original dll, probably obtain it from a dll site, to a memory stick. Boot into the puppy live cd, browse through C and copy and paste the dll.

    I'll vouch for Puppy. Very handy and lightweight way to get into Windows through the back door.
    Its got to be worth a try, else I fear a re-install will be on the cards. Sure you don't want to be doing that!

    I'll try Puppy Linux now. Is the official website http://puppylinux.org

    Thank you.

    Edit: If you can run the sfc /scannow it should replace that .dll
    SFC /SCANNOW : Run in Command Prompt at Boot
    System Recovery Options
    Startup Repair
