No Formular visible

I installed the plugin a few days ago and was working well. I also created already one formular (thats why I know how it should look like) but since the update I cant see it anymore and cant make any changing on it. I already deinstalled the plugin and installed again, but still the same problem. I really liked the pugin and was going to make the first newsletter for our page… now I cannot proceed anymore 🙁
