Problem opening jpeg file after saving it from photoshop

Question

I have been using Adobe Photoshop Elements 4 for years and have had virtually no problems.  Today I edited a picture from windows "my pictures" file and after editng it in photoshop, I renamed it and saved it as a JPEG back to the original file.  It came in a an unopenable file.  What is wrong.  Just to note, recently I updated my Norton and used a Norton tech, who took conrol of my computer because of certain issues. She deleted some programs and I am wondering if certain drives were affected.  I reinstalled my Photoshop Elements 4 from my softward CD in hopes that would make a difference.  It did not.  What could be the issue?

I did it...  I figured out the problem.  Incidentally, there must have been some formatting changes in photoshop that took place since I last used it with success.
The steps I now took.  I opened up one of my JPEG picture files, opened up one of the pics with photoshop, edited it.
1. Clicked save as
2. The box came open as to where to save and I saved as JPG file plus I checked the "as a copy" box clicked OK/save
3. The next window that came up was the JPEG option box and I checked the "Preview box" and save
4. A window came up in photoshop asking if I wanted to save (the edits on the original) I clicked no because I wanted to keep the original as is.
5. I closed out of photoshop and there was my edited picture in "my pictures" 
I am so glad that I got this all worked out.  Thanks to all of you who tried to help me.
