If you get an error try the following first:
Please right click on this link and click "Save Target As...", save it to your desktop then run the program. The program name is "FBCA_crosscert_remover_v112", if you have the old v109, please replace it with this newer version. It will open a command prompt and run. It may ask you to delete certificates - click yes to each one. When it prompts you to press enter to continue, do so (this will happen at least twice). It will then close. Make sure that you close all Internet Browsers that you had open, then go back to the HRO web page and click the MyBiz/MyWorkplace link again and continue.
