Found the problem of sometimes on COOP vs AI champs leave the queue making then a timer to start a new coop vs ai game. It was not clicking the random button. So now I will keep trying to click till it works.
I also created a different .exe for the coop vs ai for testing.

You just put next to the NHC3.exe , have the settings COOPID, COOPpath and Gamemode 2 or 3.
And it will work.
Also found the problem for sometimes he doesnt start a new acc well by not clicking on the avatar or something.
I believe its due the machine it's laggy, he clicks but not applies the click, so I will do reclick till it checks on it. next update will have this, this will help vms that are laggy.
Also I suggest people to do 1-15 on normal mode, not with COOP vs AI.
To do 1-15 it's necessary 170 games of gamemode=5 in 1v1 TCS.
I say this because on COOP vs AI you gain more exp per game if you have higher lvl, so doing 1-15 on coop vs ai it's waste of time.
