You have an expired licence somewhere.

From the screenshot it appears that you are using an OPC DA server. Why? Ignition has the Allen-Bradley OPC drivers built-in.

You're not giving much information to go on.

Has your Ignition 2-hour trial licence expired? You reset it by going to the gateway web page, login and reset trial.
