Is there any way to select my business account after logging into my personal account?

I have tried logging out and then re-opening lightroom, but before I can choose the other account I am automatically logged in as my personal account. My personal account is expired (the one that I am logged into) and I can't access my business account that is not expired. I managed to log into the business account using the web interface, but I can't save photos locally. This is very frustrating. Do I need to uninstall lightroom and re-install to be able to choose the right account?
