The QISoft website has undergone some changes with the addition of a QISoft Community, and to incorporate this, a new login system. All you need to do to access the Community is register for a new personal QISoft Web Account and if you have a QISoft Support agreement the same account will give you access to QISoft Support too.
To register you need a valid QISoft licence key (you can find your key by opening QIS, clicking Help, then About QIS and selecting the Licence tab) or an old QISoft Support Login.
Once you have registered you can login to your personal QISoft Web Account from any QISoft.com webpage by clicking the 'Login' link in the top right corner or visiting the Community or Support sections directly.
