I forgot my PIN number. I want to send it to my e-mail, but my e-mail is invalid. If I want to change my e-mail to a valid one, I have to enter my PIN number, WHICH I don't know. I can't report this bug either, because my e-mail is invalid. Please help me!

When you say that your email is invalid do you mean that you don't use it anymore? Because if you still have assess to it you should be able to send it to your old email, and then switch it once you have your information. Other than that I don't think there is anything you can do.

there is something you still can do. There are only 4 digit numbers. 10,000 numbers to be exact. Everyday you can try and cross off 5 numbers. After 200 days (max), you can get it...
