There is one upgrade issue left that i cannot fix. I reported it here already http://community.invisionpower.com/bugs.html/4-0-0/beta-2-create-new-advertisement-issue-r49180/  . Maybe someone has a hint for me

I'd recommend leaving discussions regarding bugs in the Bug Tracker, so the people working to resolve the issue can keep up with the discussion, having it in two different places won't speed up the process, it will most likely slow it down.
