Black Screen - New Server, Need HELP!

[Xamven]

Hey All,

Need some advice or pointers, setup a new server using the basic windows installer, on win11.
All seems to be up and running (using t_start_server_with_login_server.bat - no errors, and loginserver: UP status).

However when I attempt to connect with ROF2 Client (dated via dbk.txt as (Built May 10 2013 23:30:0, I just get a black screen, no server select, no activity at all.
It also does not show up an attempted connection in the login or world log files.

login.json ##
"client_configuration" : {
"display_expansions" : true,
"max_expansions_mask" : 524287,
"sod_opcodes" : "assets/opcodes/login_opcodes_sod.conf",
"sod_port" : 5999,
"titanium_opcodes" : "assets/opcodes/login_opcodes.conf",
"titanium_port" : 5998

eqemu_config.json ##

"world" : {
"key" : "removed",
"loginserver" : {
"account" : "",
"host" : "192.168.0.6",
"password" : "",
"port" : "5998"
},


And eqhosts:
[LoginServer]
Host=192.168.0.6:5999

netstat output:
C:\>netstat -an | findstr 599
TCP 0.0.0.0:5998 0.0.0.0:0 LISTENING
TCP 192.168.0.6:5998 192.168.0.6:61296 ESTABLISHED

Previously (many years ago), I ran this fine on linux, but seem to recall having to do 'something' to get the ROF client to work, like export some opcodes and copy into client folder or something (maybe not?)

Please help - tried everything I can think of.. including setting eqclient.ini to
WindowedMode=TRUE, WindowedMode=FALSE and WindowedMode=1 and setting resolution to 1280x1024 etc. (but again, don't think thats the issue, otherwise I should get a log entry when attempting to conenct right?)

Local firewalls are totally turned off while testing all this.. and i'm connecting from same computer as the server.. so not networking/port forwarding issues etc.
