First of all, Sorry for my English. I was working on a project for a month and now when i ever try to open the project, after effect has stopped working. I cant even edit the project inside the After Effect. I deleted all the third part plugins, re install After Effect but the same problem is still happen. I really need to finish the project. I have had send my project to a friend of me and he couldn't open it too. Windows 8 pro i use.
i uploaded a video to let you see my problem
I fixed it, the problem was my my nvidia program, i reinstalled it and it work now.
