I just reactivated my account downloaded the patch and everything I start game type my account and password and nothing happens I dont get a message at the bottom nothing. If anyone knows how to fix this I would be very thankfull. This only started happening after C4 came out.
Tell me, have you EVER tried playing L2 on private servers?
This login problem is quite closely related :)
Fix: go to windows install dir/system32/drivers/etc , find your hosts file and edit it so that the only line that does not start with # would be the one, having "127.0.0.1 localhost" in it.
