Problems copying files to DVD-RW

Hello… sorry to be a pain if this is a commonly asked question BUT…
I used to have no problem copying things onto my DVD-RW… even through Limewire, I never a problem copying music onto discs or transfering my photos on to cds… However, now I have a new internet connection and downloaded Nero thru a Mininova site and since then I have not been able to copy anything to a disc. I downloaded a movie and just thought it was a problem with the download… it would take 3 hours to copy to the cd but then at the end come up with an error… but now when I even try and copy photos of my C drive it comes up with the error “Windows encountered a problem when trying to copy this folder, what do you want windows to do” … please help! I have ran a full anti virus scan and it came up with nothing…

I guess you get what you pay for.
I would go to Nero site and get Tool kit for uninstalling Nero. You need correct tool kit for Nero version you have. Tool kit is free.
Run it to uninstall and hope it will work.
