Activation error keep prompt out eventhough i already having licence

Activation error keep prompt out eventhough i already having licence.
First, i try to install the license by select 'License from file' and getting this is error message:

But at the end, i manage to solve the license issue by login with my email address and get the expired date 1 year later. And able to use the ReadyAPI Pro without problem.

However, now i still getting the Activation error (1st screencap as above) every-time i launch the ReadyAPI.
Anyone have any idea how i can stop the Error keep prompting out everytime i launch the ReadyAPI? Thanks.
