My computer hates me, part 2

After working in the kitchen for a while, I decided that playing the Sims did sound like fun, so I came back in to play.  Well, the computer decided it couldn't read my Sims disk!  Never fear, I thought, if Makin Magic is being uncooperative, I'll just go find the Superstar disk.  After searching the guest bedroom, which is where all of my boxes of stuff are, I finally found the Superstar expansion for the Sims, came down to play it and... the cd-rom won't read the disk!  Neither one is in bad shape, either! 

Things are not going my way!
