When patcher downloaded the game, and i changed the ip's to eq2emulator.net in txt file and try to login its popups something about version.
Can someone help me how to log in to game?

You have to buy the Rise of Kunark or The Shadow Odyssey box set. The EQ2 Trial is not compatible with the Emu.

It's because the new trial uses the streaming client, which means you don't have all the assets local to your computer. This makes it incompatible with the EMU.
