Hi Sammie,
Sorry for missing your post!

To ensure that you will be able to reactivate LR and LM in your reformatted laptop, please remove the activation record for the laptop you're trying to reinstall your software in. Kindly have a look at this Support article for instructions on how to manage your LR and LM activation records from your BrillKids Account:
