ADE 4.5.4 won't open

[cocomuse]

[ Desktop running Windows 7 ]

I click to open the ADE 4.5 and I get as far as the small splash logo screen flashing "loading library..."...AND NOTHING MORE. 

However before this started happening, the epub(ACSM) books I would download from the library suddenly started not opening.

I've done the un-install/re-install, and the registry edit (which provided a temporary fix), and did the updates of ADE.  I've got the latest version

of ADE and still it will not open...So any help in regards to this matter would be greatly appreciated.

Thanks All

Try right click and run as admin.

If this not work check if you a my digital Edition Folder under your Documents and rename this Folder to My Digital Edtion.old. Then try to start the programm again.

Good Luck.
