I got hold of a brand new eye tracker as it looks like the cable connector was bent on my other one. This appears to be the cause of the USB error (which has now gone), but the latest version of your software still doesn’t work with the new eye tracker. All I get is the menu greyed out and a “Click to contact support” message (see image below). Event log included below. Have tried with virus tracker turned off. I believe all my drivers are up to date.
