VEXnet 2.0 Key

We received new 2.0 Keys.
I Upgraded my laptop to easyCV4 4.2.0.6.
I did a Cortex and Remote firmware upgrade utility v 4.0.1.
But when i try to down load a program to the Cortex it will not download and I get a “Master Code 4.1(Update to 3.23)” error.
If I try to down load to an non updated Cortex 3.2 it Down loads OK.
What did i miss to make the 2.0 Keys operational?

Railrhodes,

That is a very good question.
In order to make easyC work with the 4.0.1 VEX Firmware all you have to do is uncheck the “Verify VEX System” checkbox in your easyC software.
See attached screenshot.
