how to enter icecrow in the game?

hi!
I started some time ago, come from another server. I made my frostmourne account. but now it looks like I should switch to icecrow. I made the change through my account on the site. but I can't log into the game. Do I need to change the realm? it's already in the - set realmlist logon.warmane.com
Do I need to change anything else to be able to log into the game?
thanks

Everything should be fine, just log in as usual. After you log in there should be a window where you can select realm. If you go straight into character selection screen, click on "select realm" button above where characters are.
