Hi Quentin,

I'm relatively sure that I'm entering the serial number correctly, is there a way to retrieve my serial number and verify that the one I submitted is a correct serial number? I've registered it on the website but haven't received any confirmation that i have.

I bought my copy of Ear Master off of Amazon.com but when I try to input my serial number it keeps saying that the serial number is invalid. I believe that I'm entering it correctly and wondering why this is happening. Please help...
