Hi Brian,
Is it possible that you have already downloaded a previous version of LoadRunner from saas.hp.com? This message may indicate that you have already signed up for a trial, and simply need to download the latest version below:

Note that this isn't a trial version, but the full Community installer with 50 Free Virtual Users, perpetual licensed.
I hope that helps,
Shane Evans
