Problem with an epub book... I can't open Digital Editions anymore...

Hi, I just bought an epub book, and Adobe Digital Editions just try to open... and can't. Is it a bug with Digital Editions, the book, or the new update of Windows ?

Should I just wait a few days and try an other time, or try to find a solution by myself ? I really would like to read this book... and many others more.

Have a good monday,

Caroline
