How to solve: "Another user is running Tax Optimizer"

Background: 
How do I launch the Tax Optimizer?
You can launch Tax Optimizer from the Client Portal, section Home > Reports > Tax. Once you have selected a Day, click on Launch Tax Optimizer. For additional details, please consult the Client Portal User Guide
 
Requirements:
  • Tax Optimizer requires the presence of a Java Runtime Environment (JRE) installed on your machine. Should you not have a JRE installed, please go to the web page java.com and install the latest one by clicking the button "Free Java Download". Please follow the instructions on the Java download page to complete the installation.
  • Your operating system should be configured to open the .jnlp files within the Java Runtime Environment. This configuration should be automatically set during the JRE installation. If, for some reason, the file association is broken, we recommend to reinstall the JRE to instate it again.
