If you're using HUB to stream , you do not have to update bans with PAT. Its updated via streaming. Just merge our ban list with yours, set pb_sv_AutoUpdBan to 1. HUB will keep your ban list up to date.
Then remove STREAMING from update key in servers.cfg. Otherwise PAT will set up rep streaming everytime its runned.
pb_sv_banload pat_bans.datThis will not work. AFAIK in et works only pb_sv_banload /full/path/to/pb/pat_bans.dat or pb_sv_banload
