No way to log in?

Okay, so I forgot my Instagram password. After resetting my password and restarting Diapositive, there’s no way to log in. I just get a blank window. It says in the app description: “if you have any issue please e-mail us back”…that’s great if there were only an actual e-mail address/link. Instead the links given on the app page just send me to a splash page for the app. Waste of $4. G.A.R.B.A.G.E. DO NOT BUY THIS APP.
