I received this from tech support back in October:

Cd architect was discontinued as of the beginning of
September. Here is the
official word on unsupported devices.

Before you go any further, make sure you have gone to the
Sonic Foundry
website www.sonicfoundry.com/download and
download/installed the latest
version of CD-Architect. This step will give you ability
to utilize any of
the drive listed on the Supported Device Page
http://www.sonicfoundry.com/CDArchitect/drvsupp.asp?Nav=0.

If you Drive is not on the Supported Device List, you may
not be
able to use that specific drive with CD-Architect at this
time. There is
one work around to see if you drive will work as a generic
type, BUT IT IS
COMPLETELY "USE AT YOUR OWN RISK". Due to your drive not
being on our list,
we cannot guarantee any support for your device. Go into
CD-Architect and
choose Options/Select Drive. This will bring up a Select
Drive Window in
which you should select "Advanced". In the Advanced Drive
Selection window,
choose ATAPI MMC Compatible drive (if you have an IDE
Drive, or SCSI MMC
Compatible (if you have a SCSI Drive). Next, pull down the
menu for SCSI
Host and select the first option, usually 0.xxxxxx, and
repeat for SCSI
CD-R. If you drive is not listed on the SCSI CD-R Menu,
repeat the previous
step, only this time, choosing in the SCSI Host many -
1.xxxxxxx.
Once you have located your CD-Drive, click "OK" and then it
should
be listed in the bottom left corner of the CD-A window.
The final step
would be to see if you are able to write a CD. If you
attempt to write a
CD and you still get an error message, you will be unable
to use that drive
with the current release. As of the 1rst of September, CD-
Architect saw
it's "End of Life" as a Sonic Foundry Product and will no
longer be updated.
We will, however, still support requests for Technical
Support.

If you have any further questions please do not hesitate to
contact us
weekdays from 7 am to 10 pm CST at 1-800-577-6642.

Thank you,
