If none of your CD or DVD drives are recognized by the Load Disc command on the Project menu (i.e. listed in the Select CD/DVD Drive dialog), it may be due to a missing or malfunctioning ASPI layer. Please consult the ASPI topic for details on how to configure ASPI, and possibly reinstall a new ASPI layer. If this does not solve the problem you may contact CDGFix 3 Super support as detailed in Technical support to get further assistance.
Please note that CDGFix 3 Super scans automatically for available CD and DVD drives at startup only. This means that any drive that has been started after CDGFix 3 Super was loaded will not be automatically recognized. You can force CDGFix 3 Super to re-scan drives by selecting Detect CD/DVD drives on the main Tools menu.
