>>>>>I burned a CD months ago on another box. When I put it in my laptop drive, it doesn't show that any files are there, but the CD picture (properties) shows that it is completely filled. Hard to tell by physically looking at it if anything was actually written to it, but I'm pretty sure there was. Thanks!

The issue is likely that you don't have the appropriate "packet-writing" software installed on your laptop. If you install the Roxio packet-writing component on the laptop you should be able to read the CD, even if the laptop CD drive is not a burner.

BTW after having a number of issues with Roxio I've switched to Nero and never had any problems, burning CDs or DVDs. Highly recommended.
