Offset 3860 in unpacked client..
00 6B 22 00 <-- Port 8811(Default) !
---------------------------------------------
Done it with 5.20 A3client.exe

Position 38af: de 0d -> 6b 22

From 3550 to 8811

Now prob is with loginagent I suppose, because it gives errors.

First thing, client does not contain zoneagent port. Client only contains server IP and login agent port.
Second, if you want to debug using ollydbg or some other debuggers, you can go through different reverse engineering topics, just google it. Normally the process involves finding offset where the existing port/IPs are present and then changing it.
