Account recovery. (Two worlds 2)

Gentlemen, there was such a problem. Once, a very long time ago, I played this wonderful game, went through everything, played online, built a large village, reached a high level. Time passed and I bought the game on Steam, but I don’t remember the game nicknames and password, I know the soap tied to the game, letters come to it from time to time. I want to restore my online achievements, but something doesn’t work. Has anyone come across this?
Help, please, who than you can)))
