To be valid, the maintenance date for your license must be later than the official release date. You can find the maintenance date for your TotalView installation in:
installdir/toolworks/flexlm-version/license.dat
Open the file in a text editor and look for a line like this:
The example above indicates a permanent 20 token team license where the maintenance expires December 31, 2014. It will always be valid to run TotalView versions released before the maintenance expiration date of December 31, 2014, but will result in a "license too old" message if you attempt to use it with a version of TotalView released after December 31, 2014.
