hammer editor crashes

My hammer editor started to crash today it doesnt crash all time but like after 10 times when i compile my map (Actually the compile window crashes :/ ) it crashes and i have to close it. If i try to launch any game or steam tool i get this error "SteamStartup(0xf,0x0018e0E4) failed with error1: failed to take master pipe connection lock" and i cant even close steam so only way to fix this is to reboot computer. So does anyone know wtf is this??

Reboot doesnt fix this because this happened me 2 times today...

Don't run the game through hammer, load the game up manually.

And while googling, I stumbled across this:

So some of Steams pipes are broken, are they? Seems like you may need to turn a Valve somewhere.

 

Yeah, I'm out of material now.

 

Edit:

 

What seems to be the Source of the problem?

 

Edit:

 

Honestly, though. Try reinstalling Source SDK or something.

Try reinstalling?

Use a different compiler (not sure if source maps can do this though, I know cs 1.6 maps could)

Ok im not sure if its map problem but last thing before it crashes on map log is this

No that's perfectly fine. You didn't show the entire compile log tho.
