We did an upgrade of AD Audit Plus last night and now when we try to clink on the link to run it we get "page cannot be displayed"

This is the link it points to now: http://localhost:8081/

This is the link it used to be: https://support.co.lancaster.pa.us:8444/

When you clink on that link it still says page cannot be displayed.

I followed the steps in this link to do the upgrade and everything went well:

Can you tell me how to find where it is pointing now and how to change it?
