ADE does not recognize ascm files

[#1]

Hello,

I bought some books from ebook.de, downloaded the ascm files and opened them with ADE. Nothing happened... I tried adding the files to the library with cmd+O but ADE did not recognize the ascm files. Then I tried to unauthorize my MacBook Pro, but I got a message saying it was not possible at the moment and I should try again later. I shut off my laptop and retried everything several times, what could I do?

Thanks.
