I have difficulties to add Content in Adobe Connect and I'm not able to share the desktop or documents in the session, too.
error message (add content):
"You do not have permission to perform this operation. Please contact an Account Administrator for assistance."
In the sessions:
"No releases available"
But I am the administrator for this account.

It sounds like you are in the Administrator group, and no others. Administrators can do anything other than author content to the Connect server and run a Meeting room as Named Host. So, you'll need to add your user account to the Meeting Host or Authors group and you should be able to add Content to the Content library.
Not sure about the "No releases available" message. Can you include a screen shot of that message?
