[andymac19851]

Hi I have recently downloaded killing floor 2 on steam it got to 100% me thinking it must be installing but no the download started from 0% again another 6hours to redownload. I read somewhere turning the auto updates off works anyone had this problem before ? Or know why it happened my operating system is win10/64bit

This is more a question for the Steam support system. But the most likely issue is with the hard drive being either full or having a corrupt sector.
