I added new nodes from oocook5u but it still doesn't work. I can't find a solution to my problem.

Here, a c/p from the debug file :

dnsseed thread start
upnp thread start
addcon thread start
Loading addresses from DNS seeds (could take a while)
0 addresses found from DNS seeds
dnsseed thread exit

I really don't understand...
Maybe someone can figure it out!

Thanks for helping.
