XML parsing error

Hi

I have an error while i'm progressing a tutorial https://www.youtube.com/watch?v=zdR9mc39KWo.

When I submit a job, I have an message like this

Error in job Job-1: XML parsing failure for job Job-1.  Shutting down socket and terminating all further messages.  Please check the .log, .dat, .sta, or .msg files for information about the status of the job.
Job Job-1 aborted due to errors.


How can I fix it?
