Immediately after your purchase, you should receive an email from Gurucan with your login details. (When paid with Paypal, it is sent to the email address you use for Paypal.)
Also, check your spam folder.
If you still haven't received an email after an hour, you can try resetting your password by clicking the forgot password link.
You'll receive a new password within 10 minutes. Again the email comes from Gurucan.
If it doesn't recognize your email address, please leave us a ticket here.
And we will create a new account for you as soon as possible.
