Are you able to do anything which you desire with Nero now? I'm still on Nero6.6.0.18 myself and have no need to pay for software that I have no use for. When 6 stops working I'll upgrade.
Hell what the heck, you got it free and why not try it. You can always go back to 6.6. You might PM binkie7 and ask her what the current best incarnation of Nero 7 is, I don't use it? I think she uses it too. There are some buggy versions.
