The new actualization,HELP!

Hey guys…until the last actualization of unturned i got this issue. I tried to uninstal and install again but i have the same problem. How can i fix it? It says" Windows cannot acces the specified device,path,or file. You may not have the appropiate permissions to acces the item"

the game patch must not be in cyrrilic as unturned cannot read it

Run Steam as an administrator.
