The free license for Topspin 3.5pl6 has expired as of March 31, 2017. If you are using the departmental license file, you will not notice this expiration. However, if you are using the free Topspin option, you will need to download and install the latest version – Topspin 3.5pl7. Let me know if you have any questions or problems with this installation.
