I am working on an animation and I have a scene where I needed to have one character blow snow at another character. I tried using a particle system to do this, but I made so many them blender became unresponsive. I managed to deal with it at first, and when I was done with the work for a while I closed the animation and quit blender. However, now when I try to open it it won't respond at all. How do i fix this? I tried using the recover button but unfortunately it saved the blend file that was broken.
I'm not sure about it, but is your cache file still in place (can you move it somewhere else), maybe computer has a problem loading a huge cache file.
Another way of rescuing might be to create a new blend and import stuff from the other blend file that you like to rescue, if the file is really broken I'm afraid there are not many options left.
