I know this thread is pretty old, but I could not find a more relevant one to post this problem. I have installed the Pack according to instructions and had no problems. I have since decided to remove it and replace all the files with the originals using SFC /SCANNOW........but it says to insert the XP SP2 CD to fix the files and its actually in the drive. I have tried 3 XP SP2 cd's so far(all legit versions, btw), with the same problem duplicated on each CD. It may be easier to direct me to a link to the files as I can fix this easily if I have them. I am very computer literate. A little help, please?
