I have been saving all my files to a flash drive as well as saving them in increments to my laptop. But when I close the program I get an message asking "are you sure you want to close before saving your file?" and I say yes but after it gets done saving the program will not close. So I am forced to tell it the I don't want to save it just to close it out. So when I try to open my file again, I import my file from either the flash drive or the last saved file on my laptop and I'm getting the error message 33::4 and nothing comes up in the program at all. I'm just a student needing a good grade on this final!
You have not provided any system information nor told us anything about your version of AE. Also does it happen with every file? What effects and so on are involved? what comp settings? What else? You need to provide much more info. If possible you could also share one of your files so others can try opening it on their system and see if its salvagable.
