How to change the rotation of a sprite in a particle system


I have a fire particle effect and no matter what I do I can’t change its rotation. The effect would make a perfect fire ball if only I could change the rotation so that it would face the x axis. Every time I rotate it or use initial rotation the result does not change. Any help would be fine!

The effect I am using is P_Fire in the FTMagicPack01 on the Marketplace.
