Do I have to UnLicense before reinstalling Windows or reformatting my hard disk?
YES! This is very important. Installing a new version of Windows or reformatting your hard disk will destroy the eLicense database and cause the software to stop working. Any license you were using will be lost. However, licenses are set up to auto-renew after 90 days. So, if you lose a license, it is not lost forever. Try to remember to Unlicense before installing Windows or reformatting your hard disk. Try to think of this just like making backups of your important data. After you Unlicense the software, then go ahead with your system changes. When your system changes are done, you can then relicense the software by clicking the License button and entering your Order ID (registration code) and clicking the Get License button. Remember to write down your Order ID before reformatting your system.
