you will find numerous threads on the forum that reference issues with use and/or install of Roxio on the forum. Suggest a search on roxio or media manager and you will see some of those.
If you want to try again, I would uninstall, search for any roxio files and delete those, and possibly do a regedit, searching for roxio entries and delete those. I would only do that if you are familiar with regedit.
My best recommendation is to not install it at all and to use windows explorer to load you music/media on the device or to copy files off. it is way more efficient and a lot less hassle.
