Go to the Strike-Team (XWIS) website. They took over the servers in 2005. The procedure is quite annoying to some, as you need a working serial key to register for TS/FS/RA2/YR, and then you must have at least one ranked game on each username to prevent your part of the account for the game in question. Use Tunngle or Hamachi if you're not up to it.
