When Dreamtonics releases a new Major Version of the IX Product, the User has the right to decide independently whether to upgrade to the new Major Version. If the User chooses not to upgrade, the license to the old Major Version already acquired under this Agreement shall remain unaffected, and the User may continue to use, install, and reinstall the old Major Version in accordance with this Agreement. However, Dreamtonics' technical support for the old Major Version (including bug fixes, compatibility updates, and other services) may be adjusted or terminated upon the release of a new Major Version, and due to third-party technical changes such as operating system or hardware environment updates, the old Major Version may become objectively inoperable.

9. Third-Party Claims Indemnity
If Your unauthorized use of the software or breach of this Agreement gives rise to any third-party claim, loss, litigation expense, or reasonable attorney's fee, You shall indemnify and hold harmless Dreamtonics in full. Dreamtonics' total liability arising out of or relating to this Agreement shall in no event exceed the actual amount paid by You for the corresponding software.

10. Entire Agreement
This Agreement constitutes the entire agreement between the parties with respect to the IX Product and supersedes all prior oral and written communications. This Agreement may only be amended by a written document signed by both parties. The failure to enforce any provision of this Agreement on any occasion shall not constitute a waiver of such provision on any subsequent occasion, nor shall it constitute a waiver of any other rights under this Agreement.

11. Amendments
Dreamtonics has the right to amend all or part of this Agreement without prior notice to the User. Such amendment shall become effective immediately upon its publication. Your continued use of the IX Product or any of its components shall be deemed acceptance of the updated terms of this Agreement.
