So let me get this straight.
You've downloaded(pirated) the game using gofile link. Your antivirus probably deleted some files every time you run it because it thinks it is a virus then you decided to "reverify" the game you've pirated, using steam
No, none at all.
I downloaded this game using the Gofile link.
It ran good and all, but I decided to delete it afterward due to its lackluster nature, and the fact it almost overheated my motherboard after less than 5 minutes of "gameplay".
Later that afternoon/evening I decided to play a different game (wich so happens to be on Steam)
And I kept having a verification problem with
THAT game.
Wich was odd because it ran just fine earlier that day, before I downloaded Fallen Doll from the Gofile link.
I made full scans of my HD, nothing was found (luckilly), but it does seem rather odd and more than not coincidential, that the afore mentioned game suddenly did not do what it always did.
I had to fully reinstall the aforementioned game for it to work properly again, and the problem was solved.
I do however keep my fingers crossed, I haven't touched on other games yet. (I fear for my Skyrim modlist)
There, I hope I straightened it out.
