Pro Audio Support

Q:
Relaunching Pro Tools, after quitting, triggers the message, "Pro Tools hardware is either not installed or in use by another computer."The application launches fine after rebooting the computer.
 
A:
Verify that the system does not have 2 Digidesign Stream Managers enabled. The Pro Tools 5.1 installer may not remove or disable the previous Stream manager.-disable the older version of the Digidesign Stream Manager extension in the extensions manager control panel and restart the cpu.
