We have built the breadboard as indicated and installed the software, but when we initiate a recording session the software just freezes, kind of. The datalogger indicates that it is recording, but nothing appears. The device shows up in the window as busy, and continues to show up as busy even if we unplug it and try to restart the software. Any thoughts? I am sure there is some basic thing that is messed up, but I don't even know where to start. Thanks in advance for any advice!
