Issue with World.py

Hi,
I have been having some issues when trying to run the start.sh. The bottling plant pane is a black window and I get the following exception:

VirtuaPlant -- Bottle-filling Factory

• Starting World View

I am definitely not an expert when it comes to Linux - grateful for any help I get with this.

Thanks.
Jamie

The issue related to establishing communications between the server and HMI. The linux distro was separately reporting an insecure version of OpenSSL library and so would not permit the connection to be established, even on local host. This was on a Ubuntu 14.04 linux build. I re-installed the cryptography library using PIP

sudo pip install cryptography

I then did a sanity check of the other dependencies which all reported current versions. The world and him python scripts then ran correctly.
