I am running Windows 7 and Adobe Premier Pro CS4. I have been using for a few months with no problems. One night I exported movie to Media Encoder, no problems and the next morning when I made a change and tried to export again, Media Encoder starts to launch and after about 20 seconds, it gives the message that it stopped working. I have uninstalled and reinstalled several times including rebooting with no problems and it still is not working. Does anyone have any suggestions?
