KCD on Steam... won't install properly

hey Fellas… have a problem with installing KCD on Steam… so i bought KCD on 12th Feb. and pre-loaded it that i could start playing the next morning… but it seems to have failed installing it properly because the installation folder for KCD is empty and some of the game data is placed at steamapps/depotcache and …/downloading
when i start reinstalling it same problem appears… in the client it gives me timeout on server connection and stops the download at 99% and wont go further than that
PLease someone help me… i just want to play like everybody else
