Can't Upload program after VexNet

My team received the VEXNet upgrade, but while waiting for the competition switch to arrive we decided to revert back to the old RF Receiver stuff.

The only problem is now we cannot upload programs to our robot. The PGRM Status LED is constantly green.

You will need to reprogram your Microcontroller with the default master and user code using the IFI loader.

IFI Loader can be found here:
IFI Loader 4Vex

The master code can be found here:
VEX Master Code ver 7

The default firmware can be found here:
