Rocket crash at launch/directly after

The issue poped up out of nowhere. I just wanted to launch Rocket and I get “UE4 has stopped working”, that of course tell me nothing.
I checked log, and they are just cut in half like that:

[0000.98] LogEngine: Initializing Engine…
[0001.22] LogSlate: [Slate] Time to load and atlas all textures: 0.23

Or

[0000.98] LogEngine: Initializing Engine…
[0001.22] Log

Nothing useful from there.

I reinstaled entire thing on diffrent drive. Didn’t help.
Then I reinstaled Windows, and Reinstaled Rocket. Didn’t help.
Launching Rocket without default project, makes New project window to appear, but after creating new project or opening existing one, it just crash with no apprent reason.
Also to makes things less clear sometimes it just run fine… , sometimes it open map and then crash.

My Hardware:
Intel Core i5 750 2.66 (3.36 OC) - Downclocking didn’t helped.

12GB Ram

RadeonHD 7850

Crucial M4 SSD

HDD: WD Caviar Green 2TB (and 1TB)

Windows 8 all updates installed.

I’m going to make some test on my ram and HDD to make sure it is not an issue, but since it going to take quite a lot of time, I report this issue in advance.
