No, apparently she didn't create FP like we thought she might have (well we don't know for sure but Cole's answer makes it sound unlikely).

Who said PB didn't try to fix FP? She didn't want to KILL her clearly or FP would be dead already (then again maybe PB would be too if Fire King has anything to do with it). The promo art and the line "I thought I would be ready for this" heavily implies that she was actively seeking a solution to FP's problem before the princess was collected by whatever suitor, and unfortunately her time was cut even shorter when it turned out that suitor would end up being Finn.

It sometimes takes many, MANY years of work to make scientific breakthroughs.
