18 years to cool down?

Hello. I'm new to Ankulua, downloaded it from play store, tried it for a moment, said it needed 1 min to cool down or so, reboot device, launch Ankulua again, it says trial version need to cool down for 162164:18:18. I sincerely hope this is a bug, or no way I will pay for it. I don't yet fully understand how to use it. Is someone here to help me? Thank you.
