I just set all new, like you said, deleted the coniguration file etc.
But one thing I now saw is, that when I use the expressCheckout, there is no universalEmail server behavior in the pp_confirm.php file, in the normal confim.php file, there is an universalEmail server behavior.
The problem again is. That I cant open the Email Dialog when I double Clcik on the universalEmail server behavior.
I just use the wizzard to creat all the files for me.
I dont know whats wrong :-(
