Pro tools has unexpectly quit - blank sessions

Hi, first time poster here, I've been using Pro tools 11 for a year and have had no problems with it until now.



Starting from yesterday I've began to get the error message 'Pro tools has unexpectedly quit' when I so much as create a blank session, or even when I try to open old sessions that never used to have this problem. I haven't updated anything/software/upgrades or downloaded anything that would cause this problem.



I've tried to search the problem on the forum but not much advice on it seems to get me anywhere.



I tried to copy and paste the crash log but it just shows up in strange coding when pasted.



Any help is very much so appreciated.









Here are my specs:
