Session timeouts are set for your security. If you do not click a button or a link for an extended period of time when you are logged into a website (such as Digital Measures' system), your session will "time out" after a predetermined period of time. This timeout ensures an unauthorized person cannot use your account while you are logged in if, for example, you walked away from the computer and left it unattended.
The other reason that you may have received this session timeout message is because you may have bookmarked a page after you logged in. To properly bookmark the page, ensure you bookmark the login page and not a page you receive after logging in.
If you feel you received this page in error, please let us know.
