Trying verify four times and still have this issue. So steam download 800 MB again but when download is finished I see still error 'corrupt update files'. So I trying verify game cache and I see that 23 files is corrupt. From week I not play in dota, so today I get to download one or two patch at one - about 800 MB and after steam finish download it I starting dota 2 but dota quit to desktop immediately after the show menu.
