Common Issues
Pro Tools Won’t Launch
Problem
When you double-click the Pro Tools applica-
tion or a Pro Tools session file, Pro Tools doesn’t
launch, or displays an error message.
Possible Solutions
 Check to be sure your computer has the re-
quired amount of RAM to launch Pro Tools.
Refer to the Digidesign website
(www.digidesign.com).
 Try a complete restart. Turn off your audio in-
terfaces, computer peripherals and your com-
puter, and then turn them on again in the
proper sequence.
 If you tried to launch Pro Tools by double-
clicking a Pro Tools session file, do the follow-
ing:
• Close any error message.
• Double-click the Pro Tools application.
• In Pro Tools, choose File > Open Session to
open the session.
 Reinstall the Pro Tools application, using the
Pro Tools Installer disc.
Audio Interface Is Not Recognized
Problem
When you launch Pro Tools it does not recog-
nize an audio interface, or a connected audio in-
terface is not available.
Possible Solutions
 Turn off your computer and check to be sure
your cables are properly and securely connected
to your computer and to your audio interface.
 Verify that your Hardware Setup dialog set-
tings are correct.
 If you only have one interface, make sure it is
connected to the Accel Core (for PCIe) or HD
Core (for PCI) card.
 Make sure Loop Sync, SuperClock or other
synchronization connections to your audio in-
terface are correct. Disconnect the clock source
from the interface and see if the problem per-
sists.
Using DigiTest as a Diagnostic
Tool

the Pro Tools cards in your system. If DigiTest
reports that any of your cards have failed, click
the Info button next to that card. Write down
the information that appears and report it to
your local Digidesign dealer or to Digidesign
