Hi Eric,
You are correct that you need to have one of the new Service Center 9 dongles to run Windows and Bootable Diagnostics from the key. The reasons for this that the old USB devices didn't have the necessary throughput or the disk space to store or run Service Center Windows or the new Bootable Diagnostics.
That being said, the software should still run fine from the burned media, and the Service Center 8 dongle can still run the new version of DOS. Also, I have been informed that if you would like to purchase one of the new dongles, the sales team is currently offering special pricing to existing Service Center 8 customers. You can contact them via email at: sales@pc-doctor.com
Please let me know if you have other questions or issues.
Thank you,
