I am using Magix music maker free version. My trial period had expired and I was therefore asked to re register. I successfully registered and the new activation code was sent to my email. I used that activation code to activate the trial version but it is not activating. So, I repeated the above process again and this time I was again successfully registered but the new activation code was not sent to my email. I definitely gave the correct email address. But, the main point is, the new activation code I was sent did not activate the trial version of Magix music maker.
