Hello We are a research institute of the Polytechnic University of Valencia in Spain, and we have 4 helmets with eyetracker. After the last update the eyetracker has become unusable. We have tried using previous versions of SR_Runtime, but the result has been the same (or not working, with version 1.0.0 for example) In the case of being able to calibrate, the data given by the eyetracker is erroneous. It seems as if an erroneous calibration offset always makes them look up. We urgently need a solution for this problem. Or the possibility of reverting to an earlier version of the software. Regards
