My Particle System just stopped working I have a big problem, I just finished making a fairly demanding scene, And i did a render just a while ago, but then i tried importing a tree into the scene before final rendering, it ended up being a bit too much for my computer. So i deleted the tree and got back to rendering, but all of a sudden blender just crashes whenever i try to render. 

And it seems like its a problem that has occurred with the particle system, because I can't even turn it off or deleting it without crashing blender, And also before this happened i could render at 60000 particles now it crashes even if i pull it down to 1.

Another thing is, I can disable it from rendering, and at least render without the particles, but it doesn't seem to be a performance issue, as i couldn't even render it at 1 particle.

Do anybody know what might be going on? 

(Also just one more thing, I can't even move the object that has the particle system applied to it without crashing blender.)
Try selecting the source of emission set your key frames back to 0 (it must be 0 even if your animation starts on key frame 50) and hit alt+a, this should reset the animation or I might have missed the boat entirely, ether way it doesn't hurt to try
