Why Isn’t the License Code Working?

Route: FAQ - [ Why Isn’t the License Code Working? ]

If your license code is not working, it may be due to the following reasons:


1. The license code has not been entered

After purchasing a license code, you can enter it by clicking [License Code - Apply License Code].


2. You have changed your computer or browser

If you previously applied the license code in Browser A but switched to Browser B, Browser B will not have the authorization information and cannot use the license code. You need to re-enter the license code in Browser B.


3. Browser cache has been cleared

License code information is stored in the browser. If the browser cache is cleared, the license code will become invalid. Re-entering the license code will restore its functionality.


The browser being used does not support caching

DoingLabel stores license code information in the browser’s cache (localStorage). If the browser you are using has caching disabled or does not support caching, DoingLabel cannot save the license code information.


5. Exceeding the device limit

A single license code can be used on a maximum of 5 devices simultaneously. When this limit is exceeded, the user who first used the license code will be logged out.

6. Expired license code

The license code may have expired. To continue using the service, you need to renew it or purchase a new license code.

If you have forgotten your license code, click [How to Retrieve a Forgotten License Code?] to learn how to recover it.
