Adobe Digital Edition Freezes after opening .ascm file

I just downloaded Adobe Digital Edition 4 for my computer, and I've authorized my computer and the program already. When I tried to open the .ascm file my ebook's from, the file would have the contents downloaded, but the program would just freeze and nothing shows up.I can't click or do anything on Adobe, and the only way for me to shut it down is by using task manager.

Has anyone else have this problem, and if you do, how did you fix it?
