I have been using photoshop elements for a few weeks with the photo editor and the video editor. However after a few days both of them fail to launch. Only the photo organizer was opening. Is this some bug in the system or some changes in the setting?
Try going to the Organizer's Edit>Preferences>Media Analysis dialog and turn off all media analysis to see whether it makes a difference. The media analysis takes up a lot of resources and can interfere with opening the Editor. For this reason, it is best to leave your computer running overnight until the media analysis is completed. Depending on the size of your media catalog and the power of your computer, this can take several days, even weeks.
I guess I should have asked both of you whether you have registered the serial number of the program or whether you are still in Trial mode. In any event take a look at this possible solution which seems to address the problem you have described.
