Server Connect, Client connected until...

[Makwa]

I am using fresh install of Titanium (without live patch),
Using 0.7.0-833 config files.
Using Cavedudes DB.

I can connect to the server just fine.
I can login to server select screen, but when i pick enter world, it says zone unavailable (after doing it 10 times or so), and my client connected goes from 1 (me or course) to 0.

And in that screen i get this error:

unknown packet: .4233692 [92.153.64.0:15->0.0.0.0:0]
[opcode 0x0003 (OP_Unknown) Size=11]
00000: 00 06 00 00 00 00 00 00 - 00 00 00

Anyone know what this means, or the fix?

Thanks much.
