'08 Challenger Custom Tunes Disappeared from Predator

[369Hemi]

I was attempting to adjust the cooling fan temps and I might have gotten carried away with the adjustments. Now the custom tune does not appear when I plug in my predator. I have had the unit since 2010 and no troubles at all with the Predator for almost 100K miles. I bought it with 17K miles. It came with a supercharger by Lysholm.
Did I make a costly mistake? It seemed to have told me to turn key on/off two or three times. I have loaded the Diablo tunes that are stock with the Predator but it runs poorly at best.
I need to get the vehicle drivable because it's my daily driver.
Is there a reset button on my Predator?

did you restore the stock tune?
That erases te custom tune.
If you dont have the tune on there you need to reload it at a PC to get it back in the vehicle.

Thanks for your reply. Did I overlook a warning or is it that easy to delete the custom tune?
