Vinoma was not tested on mobile devices. See, http://www.plyoung.com/vinoma/
For the Apply button problem I'm guessing some error is thrown since it tries to apply the Fullscreen and Resolution options, which can't be changed on mobile. I'm just guessing but this is the most like problem. I'll create a patch of Vinoma that allows you to disable the application of these two options. You will have to modify the config window yourself and remove the resolution and fullscreen options from the settings window since I can't apply any changes to it from code seeing that it could mess up custom design that a developer may choose to do. But you are going to make the UI pretty eventually anyway so this should not be a problem.
If possible, find the log to see what error was thrown since this will help track down the exact problem. I do not work with mobile devices so I can't help on how to do this but you should find info on answers.unity3d.com or the unity forum.
For the size problem you will probably have to resize the UI elements to fit with that kind of resolution. Easiest might be to play with the Canvas Scaler options first. With the Vinoma Main Scene open, click on the VinomaGUI object and in the inspector you will see the Canvas Scaler options. Try some different options there and check how the results look in the scene view. I've designed the UI for a 1024x768 resolution and PC screens.
