IMCE filebrowser-window is empty

I have IMCE 6.x-1.2 installed and enabled.

So the TinyTinyMCE should find IMCE automatically and provide me with a filebrowser-window.

When I try to insert an image, I click the button with the tree. A window opens and in the upper line with the path, I DO have the browse button. But when I click this button, another window opens, but this window is empty. The path in the upper part of this window show the following path.

[example.com]/?q=imce&app=Editor|url@src

Why am I not getting the file browse-window?

When I get to Available updates I get the error on top of the page:
-----------------

Does this tell anyone anything?

Please help, I need those pictures to offer a userfriendly and appetizing site.

Thanks a bunch.
