Python.exe error

Hi,

 

 I am getting the below error when I am running a natural convection problem on Acusolve. The problem solves for around 100 iterations and then exits with the following message-

 

'PYTHON.EXE HAS STOPPED WORKING'.

 

I am attaching a snapshot of the error.

 

Any help would be appreciated..

 

Thanks in advance
