Can't unban with sm_unban as console.
Title explains all.
What errors or messages (debug info from sourcebans) in server (not game) console you see at this moment?
I'll test ban myself then try to unban myself with console.
Edit: Here it is:
sm_unban STEAM_0:1:61441373
L 03/02/2014 - 10:24:37: [sb_bans.smx] "Console<0><Console><Console>" removed ban (filter "STEAM_0:1:61441373")
