If the business was NOT an LLC or corporation, you may be able to sue the owner(s) personally for breach of contract--though you need to review the "fine print" of the contract and/or terms of service in detail, since they likely contain limitations on what "lifetime" means in this context, and/or restrictions on your ability to sue (many or most commercial contracts like this contain at least some restrictions).If the company was an LLC or corporation, the owner(s) are not personally liable--only the company is. Therefore, you could only sue the LLC or corporation, but if the company has been dissolved, or if not dissolved, has ceased operations or is insolvent, you will not be able to recover any compensation.
