UnrealSwarm is not running and shader compilation stuck

Since one month I am unable to compile any shader and I dont see Unreal Swarm is running. I’m not using source build, so is there any way I can run UnrealSwarm by hand?

I already re-installed and verified the engine and everything seems to be running without problems, unless that shader issue. I’m also %99 sure my antivirus or any kind of 3rd part app is not interfering with UnrealSwarm.
