Increase the fee for hanged transaction
P.S. After all above I closed BTC Core and started it again. I get notification like this "Blockchains integrity failured. Start reindex blockchains?".  I just click "Abort" button to close BTC Core and restart it. I get both tx on the right side in gray. But after 20-30 minutes old (conflicted) tx disappeared forever,  simultaneously the new (confirmed) tx painted in black. Long Life "Rolling Stones"!
That's all.
