Answered question
I cannot figure out how to go from numeric entry to alpha to install my activation code. Good start.
Can you copy/paste it from another app?

You can activate from your PC, it would be easier for you
Depends on your phone for the Keyboard change if it's an iPhone press the 123 button to change to numbers.
But it would be easier to do it on a PC or Laptop
Just do it from a PC instead if your not able to switch your Keyboard.
