"Rust Launcher Error: FatalError - Game startup failed. Error Code: 201"

I’ve been playing rust since like 4 months ago and I had few and normal problems like everybody (related with the development of the game), but today I tried to start my rust and I received the following message “Rust Launcher Error: FatalError - Game startup failed. Error Code: 201” and I just can’t play rust … I have it on steam, and it’s updated and I’ve unistalled it and reinstalled i and this seems not to work … Any help?

I’ve been looking in the web for a solution to this problem, but I haven’t found anything.

System specifications:
Alienware M17X
Windows 7 Home Premium, 64-bit
Intel® Core™ i7-2670QM CPU @ 2.20HGz 2.20GHz
4 GB RAM
500 GB HDD
NVIDIA GeForce GTX 560M 1536 MB GDDR5

U need more ram 8gb min with 16 recommended

I don’t think that’s the issue … I’ve been playing rust many times for a long time without problem

Haven’t found a solution … plz help

Have you done your Windows Updates?

I just did it, 2 important updates and restarted the computer … Nope, didn’t work
