Don't know how it happened, but all of a sudden DVD Workshop lost it's burning capability. It now reads "no driver available" under Disk Recorder when you select Make Disc or Burn Disc from Image. I have the Sony DRU-500A and I believe have the 1.0f firmware on it.

I have to use RecordNow DX. Works great, but I'm just wondering whay may have caused this glitch.
