I have this problem, when I'm trying to connect, I get the messege:
* Unable to connect (Network is unreachable)

I tried lots of servers, but the same thing happened.
Now, I been getting this messege for months (since September), which forces me to use Java, but I get the messege 'IP has been throttled. Please try again later' 10 secs after connection.

now, my question is: how can I gain access to mIRC?
do I have to register a copy? because if I register a copy, I'm afraid the same thing will happen. I been using mIRC for more than a year and this never happened.

thanks for your time
