.exe file disappears

[lDanielHolm]

Hi.

My .exe file for Blackwell Epiphany has started to disappear for some reason. I bought and installed the game yesterday, played for ~20 minutes, then closed down the game and went to bed. This afternoon, when I tried starting the game, the .exe file was gone. I validated the cache and it redownloaded it, but when I tried to start the game, the file was gone -again-. I thought it might be my anti-virus, but it is not in my Avast Virus Chest.

Any help would be appreciated.
