I have a DVD-RW installed in my computer. I tried to install some old Roxio software a few weeks ago and got a message that the software is not compatible with WIndows XP. I stopped the installation, but now the DVD-RW won't work. It doesn't even show up in My Computer. I've tried getting a new driver to replace the one that the old software disabled, and I have it installed, but when I try to troubleshoot, I get the message that the computer can read the softeware, but can't find the hardware. What can I do?
