[CrashOverride]

One important item that is easily overlooked is that you MUST:

Build your project first, Select the Window menu, Select preferences...,

FIRST Downloader Preferences.
1. Team Number
2. the file to download to the Robot: (This file will have the same name as your project with the extension .out) Browse for this file in the workspace/projectname/(usually Debug) ... directory

Only after you select the correct .out file will your code download. This section does NOT change when you change projects, you must remember to change this setting every time you change to a different project name.
