Sometimes Chrome can prevent users from signing in to StudioBinder. This can easily be solved by clearing old site data that's stored in the browser.
Just follow these instructions:
In Chrome's menu bar, click on View > Developer > Developer Tools
Along the top of the Developer Tools window, select the Application tab
In the sidebar, select Clear Storage
Select every checkbox and click the Clear Site Data button
After that, refresh StudioBinder, and try signing in again.
