It worked when I tried it without IDM. That's strange because I had downloaded the Nier Automata trainer previously through IDM without any problems.

Hmmmm, maybe because you try to use the trainer online?

Yes, because that worked in an older version of the trainer too. does not it work anymore?

From the CHEAT HAPPENS FAQ:

Q: Why aren't there any cheats for multiplayer games or modes on your site?
A: CHEAT HAPPENS does not support or condone the use of cheats in a multiplayer environment.

Old Souls player from PS3/PS4. I Platinum'd Fallout 4 on PS4 but got it again for PC just for mods and fun. Same sort of idea for Dark Souls. Hoping to try them all, but I got DS3 for free from a friend on Steam...but I'm awful at it... Everything moves so much more fluently and rapidly in this one. Mouse & keyboard probably doesn't help. That's why I was planning on using this Trainer.

PvP isn't my thing either. I'm disabled so I'm a bit slow and always panicked and got wound wrong whenever I was invaded in Dark Souls 1 and 2. I'm still there enough to still be able to enjoy the base game as is against AI, but I might as well be a dead stump in PvP... (you should see me try to play well in Overwatch)
Even on the PS3 I encountered some forms of cheats/hacks with invaders and although I managed in Demon's Souls with that it got worse in Dark Souls 1 & 2, so I 100% agree with CH's T&Cs about Online games and using Trainers.

I just wanted to ask you guys if there was anything new regarding the current Trainer version and the game?
I've seen a lot of mention of "softbans" from FromSoftware, even on people who claim to have not played with Trainers or other cheats while Online. Could someone help explain what the softban is and what it does to you playing the game? Does it just stop you from interacting with other players, assists or invades or does it lock out other online stuff like Covenants? (it took me months to figure out Covenants in DS1, but I assume they have Online-only ones in DS3 too)

Also just looking for some tips about the cheat functions. I'm sorry if this is something obvious, but how does the Max Flasks/Items cheat work? Do you activate it on an item you are about to use and it then using it doesn't use the item or duplicates it?
The demonstration video showed a Soul item equipped but showing 0 of said item. Is that a case of deactivating and reactivating the cheat to get it to work for the Soul item or something else?
Say if I used the Max Flasks/Items cheat, could I use it to dupe a Boss Soul to help level up without messing with other stats without worrying about using the Boss Soul entirely before making a Boss Weapon with it?
