hi, just installed BF2 complete (incl. cd keys) with bf2hub and damocles mod and logged in once into an empty session of lost soldiers for testing.
on the game solo against no bots and quit after. next trial there was a ban.

have punkbuster updated and registered via BF2hub, which still gives code 2400 error.
outgoing udp 29940 is open. and after a "backup account" everything is green lighted.
maybe refreshing the same cd key counts as changing the cd key or smth.

to clarify, i have been able to play on a LS server only once, but blocked afterwards with "teamkilling" message. looks like an autoban, please consider to whitelist my account name
BF2hub resolves fine, webclient url is greenlighted, my profile is up, all firewall rules are set, ports open. i promise to behave. maybe a windows 11 issue.

Hello hspank and thanks for posting.
The problem should be solved now.

Regards,
Staff Officer S_h_a_r_k_93
