I am working on a project in Adobe Encore for the first time. I created my menu, and a timeline, but my problem is, is that when I put a make a button for the movie, I can't change the button style. From what I've seen online, it looks like you are supposed to change that in the library tab, but there is not anything in my library for some reason. Am on the wrong track? Or is there a way to download the library from somewhere else? I am using adobe CS4, and running it on a imac, i5 with 8 gb of ram.
