HELLO. I installed 8.5 (and El Capitan) yesterday. I have been working on a project and have not gotten any errors while I have been working. I am now trying to export and I am unable to do it. The time indicator keeps going up and up and up and the bar almost seems to stop moving. When I try to stop the export (command+.), the system will not let me do it. I have to force quit in order for it to stop. It has not crashed (or locked up) because the numbers for the time of the export are still moving. My specs are below. Thanks in advance.
