I took a look and version 7 of the Master code doesn't affect the CMUCAM code.
I suspect there might be a setting in the code being missed. For instance, the code may be connecting to the wrong serial port. There are three serial ports on the CMUCAM and two on the Vex controller. If the code is listening to the wrong one it won't get any messages.
Here's a description of how our camera gets connected:

See if you are doing anything different. You can use different ports, but the code has to be told which one to use.
