Let me try to help.  I'll assume you're a Windows user.

To clarify, the .ascm file you're trying to 'download' isn't the ebook.

It's just a tag file that contains information on where the ebook is

located, plus some other information about the ebook, including its digital

rights.  The message you're getting could be trying to tell you more than

one thing - because, as is the case with many technical messages, the

download could be blocked for more than one reason.

The most common reason is't that the file type isn't recognized, or that

Adobe is not installed correctly.  It's that something else is blocking the

transfer of the information.  The process is supposed to work so that, when

you buy the ebook from KOBO, the transfer starts at KOBO, where they create

the .ascm file and then send a message to your computer to start ADE.  This

message can trigger your computer's firewall to block it, because the

firewall settings don't permit another site to run software on your

computer.  So, the first place you should look is the settings for your

operating system that control the interface.  Many users here have had

problems with Windows 7 settings, because they've found out that it has

some 'hidden' settings which have to be changed, along with those that are

obvious.

What else could be happening?  At least two other posters here have

reported problems with KOBO recently.  So, the website's technical support

people might be able to look into the issue on their side.  Don't let them

tell you all is well and that your problem is with that *&$^@ Adobe Digital

Editions, because almost everyone else has had no problems with ADE when

they go to KOBO (me included).  It's a long shot, but because problems have

started to show up with KOBO downloads, something has changed, and it's not

ADE.

Another issue: has the file actually been downloaded?  If it has, then you

could find it on your computer with your computer's utility software

(Windows Explorer or Control Panel), and then use the 'Open With' function,

specifying Digital Editions, and the ebook's transfer should take place.

ADE will add the ebook to your library, and you're set.

There are additional issues.  One could be that you've already downloaded

the ebook using a different Adobe ID setup.  In that case, the message is

telling you that you can't do that again.  A poor message, eh?  Another

could be that the link between your computer and the Internet has failed -

or chooses not to work with the KOBO website properly.

I'd start with the firewall/security settings.  Hope this helps!
