Master Password Doesnt work on iPhone 5

I bought the app when I had iPhone 4 and it worked great. When I upgraded to iPhone 5 the Master Password stopped working properly. The keyboard no longer appears so I cant enter my password anymore. Im basically locked out of the app.

There isnt an easy way to access support from the app and I dont see an easy way to report the issue on the developers website.
