Waited in Queue 20 mins, Disconnected, Duplicate login warning

Booted Lost Art through steam, waited to lad, selected server queued at #8626, I waited for 30 mins, got down faster than expected tbh and saw #57, then started to load and disconnected, Tried to reconnected was hit with “Duplicate login” message saying I cannot login because I am already in. Then it kicks me out of the game. I boot again from steam, it wans that I might have a hacked account and I am restricted for 10 mins, advises I sign up for protection services? Please help. And also why does the game have no main menu?! it takes so long to boot then it has to look for server, and no way to “try again”.
