Do you still have the original unedited/unchanged file saved somewhere. You should work with a copy, never the original. Just like pictures. That way if you mess it up, you can make a new copy and start over. From the original file, change it to an .avi file. Then you can import it into Windows Movie Maker.

Hmm, I had not read the whole MS page but basically you only need to follow the first 2 instructions. I have never had to use those other instructions myself. Remember that if you get flustered just click the Cancel button to get out of where you are. There is nothing to be afraid of when using System File Checker. You It simply goes through your computer checking all the operating system files and replaces those which are corrupt or missing. The need for the CD is so it can get the needed files to install for you. The slight downside is that it takes the computer back to when your particular CD was created which means you will be behind on security updates and possibly a service pack. No big deal there either, you simply go to the windows update site and the computer grabs whatever it needs. You are doing nothing wrong. Who knows why those files went missing. Perhaps/probably it was due to the power outage. You can of course extract and install each of those files if you wish to avoid using SFC. Follow the instructions here to do that for each file. You do not have to do them all at one time. Try one, see how it goes then do others as you feel up to the task.

It is interesting Pooh. Based on your post I downloaded and ran the program. At the moment this is still a BETA program, in other words it is being tested by those of us who elect to use it. Once all the kinks are worked out the final product will be available no doubt. On my computer it searched all 3 hard drive partitions and found 10 insecure programs and 4 end of life. However those tagged as end of life will not be removed, these are old programs I use and will continue to take the small risk they might pose. The live link to the right of each entry takes you to the needed update site for that particular program. It is one more program running in the background. Time wil tell if it stays on my computer but it is an interesting program
