Hi Mikey, please go to the Account Settings
and add your Lumion license. As soon as you have done this, you will get access to the Commercial Users
forum where we provide faster support.
Anyway, brace yourself for some bad news: your Nvidia GT640 is not fast enough to run Lumion correctly
Have a look at the PassMark
section in this FAQ post
Your card unfortunately only has 1296 PassMark points
, so your only option is to upgrade your graphics card - and possibly other components in your PC. If you would like us to assist you with this, please let us know what your budget is and what all the specifications of your current PC are (including current power supply etc).
