Is everything alright with Material Calibration App on the platform?

Hi,

After a certain time, I wanted to present the Material Calibration App in a training and I see the following error message. Not only on my computer but also on participants' computers. 

The error message does not give any helping information. 

I could evaluate the material in Abaqus CAE, which means that the data is not completely wrong.

Any help in this regard would be appreciated.
