I am also having the same issues, after EULA, I get nothing. Launcher crashes basically. The only thing that still works is the silly scrolling news articles.
Have submitted a ticket, but guess we just have to wait...... I tried to copy the L2 Essence (EU) files, but the launcher doesn't recognise them either (was hoping to be able to "repair" but nope)
Launcher Version: 2.2.0.666
