Plextor PX-712A Error Message

[Scoob7809]

I am getting a "Disc Type Not Supported" error while trying to burn a .bin compilation on my PX-712A drive. I upgraded the drive firmware (1.0 to 1.5 per Plextor's site) and upgraded the ASPI layer (4.71 from Adaptec's site).

I run the ASPICHK utility, and get the following info:

ASPI32.SYS ver 4.71.1
WNASPI32.DLL ver 4.71.1

Running XP 32 bit with 3.0 GHz P4, 1G RAM

Still getting the same error, no matter what kind of CDR I try. Please help!

Thanks!
