If you are one of the poor souls who downloaded the amusement park add-on for PAIN over the holidays, I have some good news. Sony has issued a fix and all you have to do is re-download the expansion.
During the holiday break, we discovered a terrible bug in PAIN that rendered new purchases of the Abusement Park expansion completely unplayable. Looks like the bug has been identified and squashed. Scott Goryl from SCEA updated us saying the glitch is fixed. Those that experienced the bug will want to go back to the PlayStation Store and re-download the expansion pack.
With any luck this is the start of a string of updates for PS3 titles, including LBP, and SOCOM.
