Data error messages at end of session

[skimel]

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!
