Without proper system info and other technical details nobody can say anything.
I am using a mac.
My processor is 2.5 GHz Intel Core i5.
My memory is 4 GB 1600 MHz DDR3.
Hope that helps!
Please check : CC Applications crash immediately after launch
Please let me know if it helped or not.
Thank you both very much for trying.
I shutdown my computer and it worked fine.
Sorry that I can't award points.
I can't decide who to give the points to.
So I can't really give any.
Sorry about that.
