Switch from free to Pro not possible

First off, I was using the free version but have just bought the pro version of the template euphonia. I tried to enter the license key into my free template, but your instructions are so thin or non-existant, that I cannot even find the area were to enter the license key into. The instructions you sent me per email seems to describe a different theme. You say, that I need to go to Appearance => About Theme => License But when I do that, there is absolutely no link "License" where I can enter the license. I really hope I do NOT have to re-install another pro theme next to my free one just to upgrade, as my site is already up and running and I really do not have the time to migrate everything. Your instructions have room for improvement. For my theme the instructions are simple non-existent! When I went to look for instructions for the Euphonia theme, they simply do not exist! Your drop down menu to select theme instructions are not in alphabetical order, so it also takes ages to sort through the list. A little chaotic... Then I also have a second question: in your terms & conditions it clearly states that you can use your themes on as many sites I wish. But when I look into my account, it appears I can only enter one website for activation. This is a clear violation of your own terms of conditions. If this license is restricted to one site, then this license is absolutly useless to me. Here is a quote from your terms & conditions: "All our WordPress themes are licensed under the GNU general public license. You may use your purchased theme on as many websites as you want. Please check your “readme.txt” in your theme folder after you download it." Please be so kind as to enlighten me on how I can: 1.) get the pro feature to activate in my free version of the Eupohonia Theme and 2.) how I can activate more than one websites for this theme in my account. Please be advised, that I only bought the theme as I assumed (as stated in your terms and conditions) that I can use this theme on multiple sites. As you can probably guess, I am in a hurry to get my site out to my client, so I would ask you to please respond as quickly as you can. I appreciate it. PS: If instructions to this theme do exist somewhere, I would appreciate if you can send me a link. I appreciate your timely help! Thanks, Walter
