EMode and EModeLogin open, but they have an issue connecting to the license server.

First, double-check your internet connection. Next, try restarting your computer to make sure the new firewall settings are implemented.

EMode was installed and functioning properly, but now there are issues launching EMode or logging into the license server.

Check that you have the latest version of EMode installed by navigating the installation page. Also, check that your connection module is up to date.
