LiteOn 160P6 No write to CD-RW's?

Hi – Strange problem, I can no longer write to CD-RWs – sorta.

I previously could write to RWs, such as backing up my Money data files or formating a new CD-RW, but I now get error messages saying these actions cannot be performed, either from the programs or from the Nero software that came with the drive. Yet, I can use Nero to erase the same CD-RW that allegedly could not be written to.

The only thing I believe “changed” is my installation (and subsequent removal) of DVDClone and its associated AnyDVD program.

Suggestions, please? I’m guessing a “no write” or “disc closed” bit has been set somewhere, but I sure as heck haven’t been able to find it.
