I have never seen this error when working with EPrime in the past.
I get a message of "WARNING: RefreshRate of 0 (Zero) Detected. Experiment will assume 60hz to continue. Data collection should NOT be used for time critical analysis. Please ensure your display adapter is configured with the most recent and device specific driver. (Standard Display Adapter under Windows Vista or later is not compatible) Run-time Error (Line 938) -999: Unable to obtain a valid refresh rate" when I try and run the program.
My display adapter is up to date and the refresh rate is the same as the last time I ran the experiment. Any advice?
