i can't login into game.

that sucks.

Now, can you describe exactly what happens?

when I try to copy or login appears the phrase: "You Have Used up yor eight-hour trial. Please log into your account ...... Bla, bla, bla, bla

Looks like you used up your trial.
If you enjoyed it, I suggest you subscribe.

If this is an error, and you are sure you did NOT spend all your gametime, I suggest you contact the devs via the Support page:
