TypeError:TypeError: decoding Unicode is not supported

Thanks, Michael. I’ve attached another screenshot with the full error message, but also pasting it below. I’ll using lexical decision task . Participants need to press button to indicate one of two choices - whether they see a word or non-word. This is randomised between the blocks and within the blocks. A word/non-word is preceded by a fixation cross and a blank inter-trial. When I tried to run it now, it actually runs until the fixation and then doesn’t load a word with the following message. Exactly the same program runs on another mac and a PC, but I need to use this PC for stimulus presentation in an EEG study.
