Do you have a screen capture of that message, if so please post as attachment.
I would expect that message just to be a temporary message, so re-check Catalyst and re-boot the laptop to see if can run again.
Your laptop has a Passmark of 1802, which is above minimum recommended, but there may be other reasons why the crash occurred when Lumion was rendering.
Were you rendering an image from Photo Mode, a video or an image from Movie Mode?
Also, what version of Lumion are you using?
