I'm working with Inquisit again after having been away from it for over a year...and for some reason am having trouble getting the Tobii Plugin to recognize and initialize my eye tracker. I'm using the TobiiPro Nano plugged directly into my Apple laptop with the USB interface. I used this same setup approximately a year ago to run a quick test and don't remember having any problems. The Tobii calibration software recognizes the eye tracker without issue and allows me to calibrate. When I try to run an experiment that contains the following at the beginning:

<eyetracker>
/ plugin = "tobii"
</eyetracker>
<expressions>
/ displaywithmm = display.getmmx(display.width)
/ displayheightmm = display.getmmy(display.height)
</expressions>

I get the following errors:

Tobii Eyetracker Error 30: 'Search for eye trackers on the network timed out.' [function connect]
Initialization of eye tracker failed

I suspect I'm making some elementary mistake...any help will be most appreciated.
