If for some reason you erroneously receive a copyright claim while a member, just dispute the claim.
In order for the system to clear your claim, make sure your channel is properly registered in your Lens Distortions account when you dispute or include License Code(s) in your dispute rationale. Your video will need to be set to "Public" or "Unlisted" in order for the claim to be released.
YouTube will notify you when your claim is released.
