2011 silverado needed 3 credits

I went to start tuning my Silverado 6.2L with the 6L80 trans and when i downloaded the files it had a 3rd controller it said something about a ctsv in the description of the controller. When i was in the house i bought my 2 credits but when i connected it to my truck it wanted another credit for the extra controller. HPtuner websight said i only needed 2 credits for this truck. Did i do something wrong? I am obviously new at this. Did i waste a credit? It says its Brickable in red. See the pic.

Don't read the FSCM and it won't be a problem.

Click gather info before doing a read and it will allow you to select the controllers you wish to read. Just unselect the FSCM (fuel pump control module).

I think you can also go into the vehicle details page and remove the FSCM from the file you are working on too. The FSCM requires 1 credit to edit and 95% of people never have to touch it.

Thanks for the info.
It would not let me continue till i bought the extra credit, so that sucks.
I should have posted before i continued
