I thought this game was shut down yearsa go

You can download the Gamemaster BF2 .exe in order to play on some servers. They cover Europe and America, although do not delete your original. Sometimes this .exe will cause the game to crash, as such if that happens, simply input a mic into your PC and everything will work (Something with the audio cycling conflicting with the new exe and causing crashes).

When done, just replace back your original .exe then play SP again :D

Have a nice day

it did , most multiplayer is done by the community there many methods to play online,
