cant write CD-RW's, only CD-R's!!!

[johnverv]

I have a Creative CDRW Blaster 4224, and I can't seem to write rewriteable disks anymore! Ive upgraded to firmware 1.44 (latest as far as I know), but still nothing. I can write to normal disks though. I think I can erase disks though.

Can anybody suggest any fix for this? I've contacted Creative afew times and I never get any help.

Thanks for any help
