If you purchased the pattern here on Crazypatterns, you can send a message to the author by clicking on the contact button in her profile. Or maybe the pattern has listed contact informations, then you can use them, too.

Ok, if you have any questions, you can contact me at any time. Just write a message via the contact-button in my store or via the contact details listed in the pattern. :-)
