The fastest way to recover your license is to enter your email address on this webpage.
You can use your license on all of your personal computers as long as they run the same OS platform (all Mac or all Windows).
For those wishing to transfer the license to a different operating system we have several options:
We can switch the Mixed In Key license for you at no charge, but it will no longer be valid for the original operating system. This policy has been relaxing for more recent releases such as Platinum Notes 4 and Flow, both of which provide a license for both OS with a single license.
If you want to use the software on both operating systems during the same time frame we always ask our DJs to purchase separate versions. As a special "thank you" for being a valued customer, we will give you free lifetime updates for all platforms after your purchase of a license for each operating system (edited for clarity 1/8/2013). You can purchase your additional license here: http://www.MixedInKey.com/BuyNow.aspx Please let us know if you choose this option so that we can designate both licenses for free updates.
If you purchase our entire software suite, Mixed In Key, Mashup, and Platinum Notes, we can send you licenses for both operating systems upon request.
If you only want to purchase one license, you can always use the tagged files on any computer and still view the results in your favorite DJ app.
If you need an license switched to a different operating system please write firstname.lastname@example.org. For the quickest response please log into your PayPal or Google Checkout account and look up your History tab (they should have a record of all purchases made since the opening of your account). We may need help to locate your transaction details, so a copy/paste (not a screenshot please) from the History tab will help. Also, please include the email address and name that the software was originally purchased with. We will send you the download link and VIP code as soon as we have more information.
