Hi,  I'm running Inquisit Lab 6 on my work PC am encountering an issue where some of my data is not saving. About 4/5 participants data will save into the data folder once they've completed the study no problems, but every now and again a participant's data will go missing. It's happened three times now which is quite frustrating after running a 90min experiment. I've placed a photo of the error below (sorry it isn't a screenshot I had to rush out of the lab today). Would anyone happen to know what the issue is or how to fix it?
