This frequently happens with multiple accounts. Most the time this can be fixed by clearing your cache and cookies.

In the past I had this problem too, and found the above step didn't work. The day after I was able to complete the tutorial though. So:

1) Clear cache and cookies
2) Give it a day or two
3) If there's still a problem email [email protected]

It could, however you would first have to remove cookies already on your computer. It is also a lot easier to just remove cache and cookies every now and then, rather than setting yourself up to browse anonymously.

Please send me an email to [email protected] with your account details.

Thanks

In order to release your accounts, please email me at [email protected] and provide me with your exact nickname (the name you chose after registration has been completed).

Another solution can be to register a new account because this bug has been fixed yesterday (for new accounts).

Thank you
