Sorry guys, I'm very new to Linux, but..
I noticed that the ability to add/remove programs (both the ways I had found how to do it) disappeared when I installed the release candidate.
So... How do I uninstall LinuxMCE, or do I need to do fresh install of Kubuntu AND the forthcoming release?

I have only done a test install, but I couldn't get out of the DVD window to see the menu without removing the DVD.
Glad it wasn't just me then.
