If you exceeded any of the terms of your contract, you will need to either purchase an upgraded license from the producer or remove the content from any infringing locations as soon as possible. Not doing so would be a violation of your contract, and can pose legality issues between you and the copyright owner.
Each producer operates as their own business entity and they fully manage their own content, licenses, sales, and client communication. Please contact them directly if you have any questions or concerns. You may use the message or social media options (if any) on their BeatStars profile to contact them directly.
