Acer 8X4X32 CD-RW (CRW8432A)

I have an AMD K6-2/550 MHz with 64MB PC100 and a 20.4GB Maxtor H.D. I also have an Acer 50X CD ROM (CD 650P) and I just purchased an Acer 8X4X32 (8MB Buffer) (CRW8432A-002). I have tried to use several burner programs including "Golden Hawk's CDRWIN 3.7f", "Adaptec's Easy CD Creator 3.5" and I upgraded this last one to the 3.5C version. I even got desperate and tried an HP version of Easy CD Creator. The results are not good. Only the Adaptec's version worked and it would only run at 4X write speeds and after I installed any of the other burner programs I couldn't even run Adaptec anymore. The software did read the description of the Burner as a "Acer 8X4X32 CDROM". I even updated all the drives that are listed on their web page. no help. Please help me. I have two of these burners I'm putting into these computers for customers that must be delivered in 2 days. I need these working at 8X write speeds.

Thanks,
