Lite-on LH-20A1L and Session Fixation errors

I just installed a new LH-20A1L (firmware BL02) and for some reason I get Session Fixation errors when trying to burn onto Sony +RW disks. These disks have no problems in other drives so I’m thinking this is a firmware issue. Does anyone know of a firmware update for this drive? I can’t find one on google or Lite-on.
