I and many other people that I asked have same "problem":
When we press to connect to eurobattle.net it takes a long time. Before I would connect in 1-2 sec and now it takes a lot longer (15-30 sec/I cant even remember when I got connected within a sec or 2.) and sometimes it never connects. Then i hav to exit warcraft and start again and again and again....
What did you do with server or euroloader?
