Drivers stopped working

I think i'm using the latest version of TBX (v1.0.5.5). But when I click on the Drill (in the platform Engine) the screen kept flickering and a message popped up saying drivers stopped working and now have recovered. TBX was working for around 2 months. What's happened ? I haven't changed anything. Anyone else with this problem?

BTW this happened to my laptop too, but with the actual game. I tried the original drivers but they didn't work either.
