OK thanks for this reply. Yes, I am using 2008.1.33, but I did not check whether the "e" was showing, so I do not know offhand (not in office right now). If not, I'll download the e version and see if that helps.
As for details, my questionnaire had no stimuli at all - no videos, no nothing. It was just 97 questions. And usually around halfway through, it would freeze up. But only for some people - it didn't happen all the time. But it seemed to be happening more frequently.
If I download the e version, will the survey I created transfer over? That is, I do not have to recreate my survey, do I?
