New Rust wont launch, give error. Help Please

I updated my rust game and installed the anticheat it says it requires.
Problem is that the rust experimental will not launch.
It keeps giving me the following error code.

Application Error
The instruction at 0x0162d708 referenced memory at 0xb5c48fdc.
The memory could not be written.

Click on OK to terminate the program.

PLEASE HELP ME!!
I' have no idea what's going on with this game. I just want to play.
Thanks

 

When exactly does the error occur? Is it immediatly when you select Rust Experimental in Steam when the options window appears to launch the game, or is it after you've selected your resolution and game quality?
Have you tried running the game with administrator priviliges?
Have you tried re-installing Rust?
A bit more information on your system might be useful as well (processor, graphics card, memory, ... )
And normally there should be a log file in your rust_data folder, maybe there is something in there that can point into the direction of the problem as well.

So I'd start with trying to reinstalling it and validating the game files, if the problem continues we'll have to check if we can find any information in the logs but if we can't find the problem I'm afraid you'll have to go ask for help on the official Rust forums @ facepunch.com
