Windows 8/8.1/10 Downloaded the 9/11 Client getting dll error

Your antivirus must removed that DLL from ML directory. whitelist your ML directory from your antivirus app and get new .DLL from Client_Backup.zip

 

Because ML client does hooking on processes, to detect player does illegal activities or not (ex. hacking), and this can be thought as attack on system aswell. Also pserver client is made by lots of tweaks, not by official service providers (remind that this is 'private' server, not neckson one). So it's eventually up to you - trust ML staff team and whitelist directory, playing it, or don't, and don't play.

To play this pserver, whitelisting ML client is mandatory.

Additional : not to be listed on antivirus app, Kimmy asked enlisting on antivirus app itself but she said microsoft is delaying for dealing with her task. (written on discord announcement).
