I purchase these for my MPC live 2. I received the serial numbers for each. The instructions are as follows: 
- Connect your MPC hardware to Wi-Fi
 - Log into your inMusic Profile on the MPC
 - Go to Preferences > Activations
 - Press “ENTER SERIAL”, type the serial number above, and press “REGISTER”
 
However the the serial numbers I received in my email are 30 characters long and the MPC activation inMusic Profile on the MPC only allows for 25 characters. 
What am i doing wrong?
