Talon SRX not working

[amstrudy]

So about ten minutes before this problem, the Talon SRX's were doing perfectly fine. Then we took a piece of plastic off of the robot and they stopped working. Now, I try to turn on a motor and the SRX will blink red and amber, with a few spurts of green, like it's trying really hard to turn on. The SRX's use CAN.
Thanks for the help!

EDIT:
We have tried re-imaging the RIO. A Talon SR with PWM also did the same thing. CAN is not the problem, because all of the motors appear in the webdash. I even made another tester program with just one motor and that didn't work either.
