Is there a problem with Pro Tools 7?
When Digidesign first launched Pro Tools 7, there were reports of difficulties using the DNS2000 version 2.0. With Digidesign’s release of Pro Tools 7.1 HD and the CS-4 update, version 2.0 appeared to be fully operational again. DNS2000 software version 3.0.2 or above is strongly recommended for Pro Tools 7 systems. Version 2.0 is no longer actively supported.
