URL of experiment: BIO_NUM_TASK [PsychoPy]

Description of the problem: Hello, I am currently running an experiment online. In runs ok in my computer and some particpants completed it but others have some problems like the one in the pic attached. They have an error ‘operation aborted’ when trying to load some stimuli. The experiment has many videos (around 800, 2 videos per trial). Could it be a problem of browser? Thanks a lot.

Hello again,

The problem continues and some people manage to do the task while others keep experincing problems like the one attatched. Any idea what could be the issue? The people that did it used OS ofwindows 32 or macintel. Thanks in advance
