====== Why are my registration keys invalid? ====== Invalid registration keys can be caused by a few different things. - The site name is incorrect. - Your registration key was temporary, and it has expired. - You have upgraded to a new KampData TaxEngine version. The KampData TaxEngine registration keys are generated based on the registered site name and KampData TaxEngine version number. For registration key requests, please [[kampdata:contact_us|Contact Us]]. We will need your [[dynamics:dynamics|Microsoft Dynamics GP]] registered site name and KampData TaxEngine version. ---- [[taxengine:faq:Frequently Asked Questions|FAQ]] \\ [[taxengine:Troubleshooting]]
