Following the instructions as stated in the CEM Manual to resolve the 'generate missing configuration files' message the process just spins when logging back into the UI.
The login.json file contained an erroneous Zowe Gateway section.
Release : 6.0
Component : CA COMPLIANCE EVENT MANAGER
Since ZOWE was never configured, removing the ZOWE GATEWAY section in the login.json file corrected the spinning condition when logging into the CEM UI.
