Reactivating Spine on a new computer should not consume an additional license from your remaining allotment. The Spine license system is designed to automatically log out of the old computer when you activate Spine on a new one. This means you can continue using your existing license without taking up a new one.
If you encounter any issues or receive an error message during activation, it is best to check the specific error message and ensure that you are not consistently using the license on more than two computers concurrently. If you still face problems, you can email the support team at [contact@esotericsoftware.com](mailto:contact@esotericsoftware.com) for further assistance.
