Warming shades.. crash!

I installed RUST and start… when I see the line “warming shades” I have a crash to desktop with no alert and the program is closed.
The legacy version works but not the normal.
I have win 7 64bit on a acer aspire laptop with 8gb ram, intel core i5 and NVIDIA GeForce GT530M.
Please help!

Make sure your GT530M is set as the default graphics adapter. What version are your Nvidia drivers? (Specifically the xxx.xx number.)

thank you! that was the problem…
it worked!
