Screen issue with Eyelink

I am a researcher in Canada who just updated some new computers in the lab running psychtoolbox with eyelink.

Info:
psychtoolbox 3.0.16
Windows 10
Error present for all eyelink demos & custom code

Error code:
EYELINK: WARNING! PsychEyelinkCallRuntime() Failed to call eyelink runtime callback function PsychEyelinkDispatchCallback [rc = 1]!
EYELINK: WARNING! Make sure that function is on your Matlab/Octave path and properly initialized.
EYELINK: WARNING! May also be an error during execution of that function. Type ple at command prompt for error messages.
EYELINK: WARNING! Auto-Disabling all callbacks to the runtime environment for safety reasons.
Eyelink: In PsychEyelink_get_input_key(): Error condition detected: Trying to send TERMINATE_KEY abort keycode!
Eyelink: In PsychEyelink_get_input_key(): Error condition detected: Trying to send TERMINATE_KEY abort keycode!
Error in function Rect: Usage error

Running experiment on a 'EYELINK CL 4.594 ’ tracker.

Any help would be greatly appreciated :slight_smile:

Do other PTB demos work, as this error suggests a PTB error opening a window?
