Hello,
In case you have taken over an older application of your own company, it should be that your company must have purchased a license for the control. If that is the scenario you may not need to purchase a license again and use the same.
Hence, a suggestion would be to contact supportone@componentone.com for information on licenses purchased by your company.
It would help, if you could provide any email ID that could have been used to possibly register the license.
Best Regards,
Tuhina
