windows setup problem adding/removing components!!!! all 0.0 MB in size

When I am in ADD/REMOVE PROGRAMS PROPERTIES, WINDOWS SETUP, I NOTICE SUDDENLY (EVERYTHING SO SUDDEN, NOT LOL, BUT I KNOW I SAY THAT LATELY, BUT IT'S SUDDEN AS BEFORE THESE ISSUES WEREN'T ISSUES -- WHEN GOING OVER COMPONENTS AS PART OF TROUBLESHOOTING RIGHT NOW, I SEE A PROBLEM THERE TOO -- WHERE COMPONENTS ARE LISTED NORMALLY, WHILE THE COMPONENTS AND CHOICES REMAIN listed, THEY'RE 0.0 MB in size. If I try to add or remove components anyway and click okay, nothing happens as it should after doing this. Instead, after clicking apply, it closes out. Also note that before clicking apply, where it says Description within windows setup, showing you components selected, et cetera, above that it states space used by installed components: 0.0 MB, SPACE REQUIRED 0.0., SPACE AVAILABLE ON DISK: 14238.4 MB, WHICH EXPLAINS WHY IT CLOSES. It's like there's NOTHING really there component wise. Name only. What's going on here? This may sound dumb, but could this have anything to do with my sound going? I was trying to switch some components around in multimedia which is how I noticed this problem now. Any questions, let me know. I tend to add more information then needed which may confuse some of you great helpers out there.
