ive played a small amount of killing floor 2 and that was because it randomly uninstalled itself which i had no problems with but then it wouldnt download as when it finished installing it would read "content file locked" ive tried near everything including: running steam as admin, running cmd as admin and using netsh winsock reset, retrying the 20.9 gb download, resarting my computer and retrying the download, adding a new library folder, verifying the integrity of the game files, and turning off my antivirus and firewall. if there is any fix please tell me
