Need help - Big connection problems

Hi there, i just bought the game yesterday.
Installation was ok, and then i created my warrior.

Then i had to connect on server and download some files to get in... but..
nothing happends...

There is a download bar which indicates 0% and which is never increasing.

That sounds very strange because before this i had to connect to arena.net and that was wihtout any problems. So the problem dosnt come from my isp..

Then I installed the game in my friend's computer, and EVERYTHING worked very well..

I really don't know what happens here, but what i can tell you is that i have winxp sp2 2002. And I tried to play wihtout norton, without the firewall, and without the anti spyware.. but it was useless..

I tried to connect all night long without results... so if someone can help me.. sorry for my english im french, but if you need more precisions don't hesitate..

Thank you a lot
