Network error on your end. Possibly a timeout.I don't know if this is a known issue or if it happens to just me, but it will say it's finished downloading a title when it is about 80% done and it won't let me resume it unless I delete the downloaded files and try again.
Close the app and retry the download, it should continue where it crashed.

Java 9 is still preview. It seems the JavaFX's ButtonSkin class has been deprecated, or hasn't been added to it yet. So, you will need to use Java 8u111. Sorry.Using Java 9 on Linux (Ubuntu 16.10), it crashes :

Java version :
Code:java version "9-ea" Java(TM) SE Runtime Environment (build 9-ea+140) Java HotSpot(TM) 64-Bit Server VM (build 9-ea+140, mixed mode)
I'll add Java9 support until it's released in 275 days.
