Removing Serial Number from MPC

Quentin_Lewis

I am using a Windows PC to upload Native Instruments Expansion packs. I recently purchased two of them and mistakenly registered the serial number directly to my AKAI Pro MPC instead of registering it directly to my inMusic application software via Windows. As a result every time install and download and extract the expansions on the MPC the "contents" are missing and contains nothing but a blank file. I need to unregister the serial number from my MPC and register it again but to my inMusic account via windows. Can someone give me any tips how to solve this. This company takes your money but is nowhere to be found when you need help.
