Help! : finalize DVD+R

I write my data on dvd+r (start multisession) and I didn’t select “finalize disc”.
Then right now I would like to finalize it, I’ve try on nero disc info tool (“Close VR disc”). It didn’t work(error message “Unspecified Recorder Error”). So I try another way by create new project and select continue multisession disc.
There’s other problem, Nero’ll ask us to select the track right? I can’t select any of it(there’re 2 track in 1 session) so i can’t continue :sad:

plz help me!!! what should i do?
