CDSpeed 3.80 falling over

Hi,
I’m having trouble getting CDSpeed 3.80 (from cdspeed2000.com) to produce a test CD (Tools -> Create Data CD). At a seemingly random time after CDS starts writing, I get a “NO ADITIONAL SENSE INFORMATION (000000)” error.
Does anyone know what causes this error? The drive is a Liteon LDW-851S with Omnipatched SOHW-832S firmware (VS0G). It also seems to lock up the drive - I have to reboot to re-enable the eject button :frowning:

Thanks,
