It seemed new Aspi Layer from CDRWin isn't working also into Win98. Check the following email I got :
"..I downloaded and tried the CDRWin ASPI Drivers. I had nothing but trouble. My system would completely lock as soon as I tried to record a CD. I deleted the drivers and I will stick with windows ASPI until Jeff Arnold gets his act together. My CDRWin is registered. My system is as follows.
Running Windows 98
Plextor UltraPlex CDROM
Adaptec AVA-2910C SCSI Card
Yamaha 4416E CDRW Drive .."
Me on the other hand didn't had the time to install new Aspi Layer. Will try to do tonight..
