The dongle problem is probably just a fault in that little switch on it.
If you have a multi-meter try testing the pins while you flip the switch to see if it's operating properly.

The motors not running is probably a separate problem.

How far did you get in your setup?
Did you bench test the control system?
After that did you reflash the cRIO and the Driver Station?
Were you able to set your team number on the DS?
Is your DS plugged directly into the cRIO with an ethernet cable or are you using the wireless?
Has the wireless router/bridge been setup?
