Obviously something in the Dinput8.dll is derped or bugged. But here is what I did to get it to work.
1. Open up 2 clients
2. Set resize them so that they both fit on your screen.
3. Type in the info on each client.
4. Login right away on each one after the info is typed. (You only have a few seconds to do this or else it'll fail.)
5.Hit start (log into world) then, quickly, go to the other client and hit start.
6. Do what you normally do with 2 clients open.
WARNING: Channel changing on either client will result in an imediate HS error.
Hoped this helped whoever was having difficulty with getting their Multi-clienting to work.
