    Data error messages at end of session

    I am encountering several error messages when I run my experiment in MediaLab. This is happening at the end of the experiment and in both conditions.

    Here is the info about the programs:
    MediaLab version 2008.1.13
    DirectRT version 2006.2.0.28

    These are the three error messages I receive each time:

    1. 75 Path/File access error
    2. 52 Bad file name or number
    3. Error opening SPSS file for append. Make sure file is not already open.

    Thanks for your help!

    Similar issue here but doesn't look like there was a resolution:

    These errors all occur (in most cases) because MediaLab can not write new data to the data folder. There are a few reasons this can happen.

    1. Data files are already open (although ML would normally tell you this at the start of the session)
    2. Data files are read only--this can happen, e.g., if the experiment and its data folders were copied off a CD which causes all the file to become "read-only"--right clicking the data folder to check for "read/write" is a good check here.
    3. Data files are located in a folder that has user rights protection (see link above)
    First thing I would suggest is to ensure that *all* files and folders are closed when you start your session. Does that make a difference? If not, then the next thing I would try is to backup and then delete the data folder and run a test session--does that resolve it? It may be that there is a corrupt file and starting fresh will resolve it.

    If none of this works then let me know and we can do some more in depth trouble shooting.
