Crash on application launch.

Hello.
I've been struggeling for two days trying to resolve this issue, but have not had any luck so far.
Whenever I launch the application, and press login. It crashes and gives me this error message.
I've browsed your forums but didn't really find anything that helped me.
So far I tried uninstalling and reinstalling, updating Java.
I tried the Ender's client.
I also portforwarded 1870 and 1871.
I hope you can help me.
