Is my Pio broken?

hello, heres my problem; after successfully burn one disk with my Pioneer DVR-110D, the software stops recognizing blank media, so I have to restart the PC to make another burn… been using Nero 6614, clonecd 5261…TY MCC SONY and other media, my current fw is 8.37…any ideas, thanks in advance…

Then please post a logfile from Nero, but remove the serial first.
