There is an issue with Chrome version 59 that affects a core function the way FC currently executes. Without getting too technical, the calculation of lineups runs in a separate process on each users computer, allowing the continued use of FC while the calculations are happening. In Chrome v 59 this background process keeps terminating prematurely resulting in the message that only X lineups can be calculated. This number varies from calculation to calculation (without changing anything) and is seemingly random at this point. If you calculate a few lineups, then use the calculate more lineups button, you will see the calculation will continue because the background process is then restarted.

We are working on determining the exact cause now, and will get a fix out asap, but I do not have an ETA at the moment. This is obviously a critical issue and we are treating it as such. In the meantime, IF YOU HAVE NOT UPDATED CHROME, PLEASE WAIT A FEW DAYS. If you have already updated and are experiencing this issue, your best options are to either use Firefox for the next few days, or you can download the previous version of Chrome (ver 58) from the following links. You would need to uninstall your current version and re-install the appropriate one.
