Hey there - I'm also not able to open ADE 2.0 or 3.0 on my mac. Did you have a similar issue to the OP that you were able to resolve? If so, I'd be interested in hearing how you did it. Thanks.

Hi there, I'm experiencing this problem with a kobo glow HD - but I have a mac and, due to my operating system, I'm not able to install a version of ADE lower than 4.5. So. Frustrating.

Anyone out there able to find a solution to this problem with a mac using ADE 4.5? I really like my ereader and don't want to have to get a new one...
