Hi @Dwi Laras Syahrina,
A couple things:
- The Trial is only good for 14 days. If that time has passed, then you've already used your trial.
- The Trial tethers itself both to an IBMid and the hardware id of your device. So if ever you have activated a trial on this device (with any IBMid) in the last 365 days, then you've already used your trial.
I've initiated a contact request with you so that we might interact privately. I will collect your personal information and then research what may have gone wrong with your Trial activation.
