YEAH! Thank you guys!I don`t want to install all thos skins and other things again! Srry Can you just put that item! And that`s all! If that problem will stay - I will reinstall 
Blackwood.wld
I don`t know if this section is right for this problem... 
I was playing in one Demo server, then it lagged, and 5 sec later There were monster big cones, tyres, ramps and other things. Now it is funny, because i didn`t downloaded and overwrited anything, but not this file is crashed and when i play in Server, it all the time shows - Can`t find blackwood.wld
I tryed :google:, but it showed all other things, but not this file...
Can anyone put the default blackwood.wld?
