Problem Logging In

I just downloaded the Full Game Client and I was really looking forward to playing but it says:

<--
Disconnected from Server At:01:07:18 AM on Tuesday August 14th
Drop By Error<<--, Server Drop, ISP Issues.
-->

I have read the other posts about this problem and I have tried everything to fix it. I have tried the backup server, re-installed it, I even allowed it through my firewall but to no avail it still wont let me connect. Does the sever turn off for the night or something? A prompt reply will be greatly appreciated.
