Ah, troubleshooting, isn't it fun?
Let's see:

Operation:

• Are all your Driver Station status lights showing green?
• Robot Enabled?
• RSL steady-on with a brief occasional blink?
• Any status messages on the Diagnostic tab?

Hardware:

• Is everything wired like this nice LabVIEW diagram demonstrates? (Taken from the front panel of the Solenoid with Compressor Example.)
• Are the three Digital Sidecar voltage status lights glowing brightly?
• Is the Spike status light on?

Software:

• Try running the Solenoid with Compressor Example from the Developer Account as a working baseline
• Are you using the Driver Station application from the Developer account? (Make sure you've exited the Driver account altogether.)
• How are you running your code-"Run as startup" or "Run" from Robot Main?
