Hey guys I hate to ask such a simple question, I got a 2nd Cortex,

But this one needed to be installed inverted.

I downloaded the Cortex software, connect it up, got it to show on the software is vishion 13, etc. But I try to push the invert option and the equal signs on the right turn red with a slash, I go to the first page and try to send and it doesn't seem to do anything.

What am I doing wrong. Thanks
