From leading man Travis Williams, comes this post on the official PAIN site:
"I am actually writing this update in LAX because my flight was just delayed for an hour AGAIN (I am headed to the Game Developers Conference). This past month has been quite the journey. I must admit that it has been a learning experience that wasn't as PAINless as I initially expected. The good news is that if you are still with us then that update is right around the corner. Right around the corner like Thursday the 21st of Feb. This update includes the leader board reset (and the fix to the score exploit) It also includes the Free Single Player Fun With Explosives Mode and Hung Lo.
Single Player Fun with Explosives comes complete with it's own Leaderboard too. Lets see how long it takes for you guys to beat my personal score. I will also answer a few questions (demands) that I have been promising everyone for a while. I hope this will shed some light on what is going on with our PAIN."
