When i am logged in and want to change a node, i get the Error Message:

"The content on this page has either been modified by another user, or you have already submitted modifications using this form. As a result, your changes cannot be saved."

If i disable the Module everything will be okay.

I don't think that's possible, this module isn't doing anything with nodes. That's the message from Drupal core that you'll see when you're trying to edit a node that's since been edited by (usually) another user.

The code is in node_validate():
