ok. I tried both
Cleared recent history from my firefox AND set the timezone of my PC to Tehran(where I live) and adjusted the time to the correct one. didn work.

and an irrelevant question to the thread,
as i said I live in Iran, Tehran. my country has no credit or online payment services, therefore I am not able to pay and get tokens online. Is there no other way to get quick tokens like getting 100 tokens or at least 50 tokens in a day?
