New PAIN downloaders experiencing not-so-amusing glitch

There are many people that are new to PAIN and its various expansion packs. The "Abusement Park" add-on is corrupted for anyone that downloads it right now. Many are blaming the recent 2.53 patch, which adds a free character and YouTube support to the game. "If you did not have the Abusement park addon downloaded from PSN prior to the update the level is destroyed and unusable, Items fall through the landscape the background image is blank white and the level is unusable."
