Burning issues

Problem seems to have come for no reason,downloaded some nero 6 updates for bro as hes only on dial up,so saved to documents opened docs and right click file down to send to E as D not listed for some reason.Icon of folder appears to be sending to drive but nothing happens,ctl alt,del shows not responding and I cannot close it either,have to restart pc.Have Nero6 reloaded ,tried uninstalling both drives and ide controllers,Both drives work fine on a straight copy of cd or dvd on dvd drive.Drives are Pioneer dvr 111d and sony cdrx 230e any ideas.
