If the Safety Config is tripping, then you should see an error message on the Diagnostic tab window eventually. You probably have to scroll back through all the messages carefully.
If you suspect it, then you can Disable the Safety Config, but I'd put the robot up on blocks to test it, so that if it tries to run away it won't get anywhere or hurt anyone.
In fact, I'd put the robot up on blocks until you get this figured out.

Lost communication can also be caused by a poor DLINK power connection on the robot. If you have the robot up on blocks try directly connecting an Ethernet cable between the laptop and the cRIO to test run.

You can use a Diagram Disable structure (same menu as the programming loops) on the camera code or delete it altogether if you don't plan to use it. Code for the camera is in Begin.vi and Vision Processing.vi and both will need to be disabled.

The FRC Driver Station Log Viewer should show up on your Start -> All Programs menu. It got installed with the Driver Station update.

Just check the voltage readout on the Driver Station whenever you see problems.
