You don’t have to create new worker from the pool,
Just change the worker name in .bat file and than after some minutes the new worker will opened himself...

The mining pool server is on update and not all bugs comes from the miner,
But in last hours it’s seems that many times the miner disconnecting from server beqause of this update,
I hope that finally they are doing good job with all that updates and hope the good luck will comeback to the pool soon ...
