No, it is possible that there could be an issue with the License Key. There could be several reasons why DriverAssist is not accepting the copied and pasted License Key. It is recommended to double-check for any mistakes, ensure that there are no extra spaces or characters, and make sure that the License Key is valid and compatible with the version of DriverAssist being used. If the issue persists, contacting DriverAssist support would be the best option for further assistance.
