Moving this discussion to the Premiere Elements forum.
Welcome to the forum.
I am not sure how a failure to launch Organizer would affect the Functional Content in the editing portion of the program, but that should be addressed. Do you get any error message, when you attempt to launch Organizer?
How long have you let the program run, after attempting to launch it? If you have a lot of media files on the computer, this can take a while.
As for the Functional Content, Themes, Titles, Menus, etc., do you see those in the galleries in the editing portion of PrE? If you do, they likely have a blue banner in the upper corner, indicating that those need to be downloaded, to be used.
Likely two separate issues.
