Hi, I ran the tutorials of Pipeline pilot protocol "Calculating Yield Stress and Critical Distortional Strain", in the Materials Studio collection. I ran the protocol several times and always receive the error. The error message is attached below. Can anyone tell me what this error means and how to fix. 

Thanks a lot.

Sincerely,

Leo Tai
