Do I need to do a separate installation to play Red?

[Jahdu]

Been playing on blue for a while now and want to try red but every time I try to select the server nothing happens and after a while the screen reverts back to the login screen.

Do I need to make a separate installation to play Red? I'm playing on an iMac if this makes any difference?

Don't need a separate install.

lol Freezi... maybe. Don't know what the issue might be... Will try again tonight.

No resolution so far... I can select blue without a problem, only happens when I select red.
