Yes, but my question is why did I get drops with games I haven't played more than 2 hours?

Hello, I'm using this software a few days ago, and there is all correct, but I'm scared because I don't know if I can get a ban from Steam. I have all the VAC games in the backlist for more security but I want to know if I can get a ban to close my account or something related.

More things... Why did I get some drops with games as I dont played for more than 2 hours? Im too scared for this too :(

I can't because they are from VAC servers and they can ban me.

Hello guys, today I see a text documment called "error.txt", I opened it and I've seen this:

I think that's because i've got the games with secured VAC servers in the blacklist but I dont know why I get this error.

PD: When I dont have any game in the blacklist, this error don't appears.
