Chief Delphi - Problems with SmartDashboardFX (SFX)

I have two independent problems with SFX. First: I cannot get my plugin to work. The log is

Code:

Using Java 1.8.0_25-b17 and JRuby 1.7.23

Release/Built? true Version Identifier: jenkins-SFX-42-42-c6c3c5118c391af8bd0faf54c9713f8e89806c6e

Exception in thread "JavaFX Application Thread" org.jruby.exceptions.RaiseException: (NoMethodError) undefined method `gsub' for nil:NilClass

This only happens when my plugin is in the plugins folder, so it is clearly an issue with it. However, I can't tell what is causing the issue, since I'm not calling any gsub method.

The second problem is more generic: When I attempt to follow http://wpilib.screenstepslive.com/s/...ch-with-the-ds, it doesn't work, but when I follow the trouble shooting steps, they have no issues.

Thanks for any help
