Hello,
I bought EarMaster on Amazon.com. I can't install the full version because after I put the serial number from the front cover there appears information that this is not proper serial number. I did it several times with BIG and small letters. What is wrong?
If you just sent us a registration (Katarzyna form Poland), then you didn't read the digits correctly. I have just sent you an e-mail with the correct version of your serial number.
Have fun using EarMaster!
