Using free AND licensed accounts

I recently licensed TeamViewer for use at work (local gov't). Since licensing the client on my work PC, I am no longer able to use my personal account from that client. I can sign in, but when trying to connect to a contact, I get "Your trial period has expired," when in fact, my licensed period has only just begun. Is there a way to run licensed and free accounts concurrently, or did I just make a huge mistake by purchasing your product?
