CWA + KOBO = Cannot open kepub

[KumanduS]

Dear all,

after alot of problems to get CWA running i finally did it!
Now i have another problem, kobo can see my self, and it get updated, i can even donwload the book. but every time i try to open the book i get the "Oops! this document couldn't be open". I am guessing that i am doing something wrong. can any one help?
Best regards,

I have more information. I tried to put de kepub dusing pc conection to the kobo and kobo simple ignores them. If i try to put an epub the kobo will open the file. If i delete all my kepub files and then sync with kobo (to ensure that the sync uses the epub) i still get the error on opening the epub file. Can someone help me?
