Computer won't recogize disc?

[Iris-Way]

I just played my Family Fun Stuff, then exited, then went back in again 10 minutes later, but now it keeps telling me to make sure my disc is in. I took it out cleaned it about 5 times, then put it back in, but it is still doing this.
=[
Any ideas?

That has happened to me.

Try restarting your pc w/out the disc in and it should work.

That's what worked for me.

Yay! Thank you. It took a couple of restarts, but I managed to get it up again.
