I had this same problem on my last computer and the distressing thing is that after a few days of normal operation my NEW computer is doing the exact same thing. The "a serious problem has occurred" error message pops up when I save a project. Then eventually the project will not even open, the error message pops up instantly. I have TWO plugins on the computer - thought I found the one that was making it crash and removed it - the computer worked brilliantly for a day. The next day the error messages came back so removed the other one - same thing, worked brilliantly for a day then the error messages came back. Now I'm out of plugins to remove and a computer that won't save anything. What could possibly be the problem? I can't make any sense of this but maybe one of you can - here is the log:
Any help or tips are greatly appreciated.
P.s.
