Disconnecting every 30s

Hi, i am having some issues to play with the client tbc downloaded here on warmane, i just finish the download and put it on c: so i can play, just as i've done on WotLK. But it's a strange issue, when i start the game it just get a black screen, i close it by the task manager, i've read something about update video driver, windows update, compatibility mode, but just doesn't work, the only way to start the game without black screen it's with compatibility windows XP sp3, but with that i get disconnected after 30s all the time. Maybe someone know how to fix it. Thanks.
My pc is running windows 10 pro, last update, video card gtx 1050ti with last driver too.

Do you have FileZilla installed? A friend had an update on FileZilla and it caused ~30 second hangs.

No i don't, i just figure out that if i start the game on windowed mode it runs normal, just not fullscreen, still not understanding what happening because my wow WotLK runs perfectly on fullscreen
