Can you do something about D4RR3N vs. ssbbm - ssbbm is very inactive (logs in for one day, doesn't log in for another 4, etc) and that game is holding up your entire tournament. I'd just give D4RR3N the win, he's waited long enough and is clearly the more active person in trying to get the game done. ssbbm and D4RR3N have had MORE than enough time to get the game done honestly.
Also, never give a 2 week deadline for a semifinal...that's way too long for 2 games!
