There are several possible explanations. Here are the common issues concerning token and
cash balance issues:
1. Users are only permitted to have one account. It is possible that you might have created an additional account by mistake. Double check all email addresses and Facebook accounts you own to see if you might have accidentally created a duplicate account.
2. More than 90 days have passed since your last login and your account was deleted due to inactivity.
3. You spent tokens to redeem a prize.
4. You cashed out your balance with PayPal.
