EMET v5.5 Pinning Rules Expired

We are running EMET v5.5 and the Pinning Rules that installed with the product have expired. Here is a portion of an application event log entry:

 EMET version 5.5.5871.31892

The PinRule "TwitterCA" expired on 9/1/2017 12:00:00 AM and will not be used to validate certificates, please update this rule or delete it.

What needs to be done to correct the situation?

Thanks,

Sue
