Some security programs will block a program's access to common Windows functions. Webroot SecureAnywhere is one of them. This can cause issues for ESPlanner when it tries to do rather routine things.
An example is pasting earnings from the ssa.gov site into the Past Covered Earnings tab of Social Security. If this applies to your system, you may see the error "No Earnings data was found on the clipboard" when trying to paste.
Resolution: A change is required in Webroot to allow ESPlanner to access clipboard.
