Thanks for getting back to me. Yes, we are saving the data locally to the same folder, and all of the sessions are being run on the same computer. I think that I may have figured out the problem - it appears that if you exit out of the program incorrectly (i.e., using the Windows button on the keyboard and then right clicking on the tab at the bottom of the screen to exit) the individual text response files save, but not the SPSS data. Does that make sense? I originally didn't think that was the problem since some of the data was saving, but I was able to recreate the missing data when I ran a test and closed out that way. I assume there is no way to recover the data that we lost, but please let me know if there is a way.
