PPT talk button error: Failed to connect to COM4

[tobin]

I'm not familiar with the warning messages you're seeing at startup.

Do you normally set your PPT to communicate via COM4? If you're usually using VRPN, then you ought to set that port as your communication port. You can adjust these settings in the "edit options" window which you can find by starting the calibration wizard.

Please let us know if you continue to have this problem.
