Client startup error on new computer

So I got a new computer a while ago and recently decieded to download FAF Client to play again but I get a java RuntimeException. Can anyone help with this?

The error should display below from a screenshot I took:

That's a bug in 1.4.2.
You can either download the latest rc here:
Or you make sure only 1 instance of the client is running and no other software uses port 8080.
