Yesterday I made a clean install of snow leopard on my 2011 iMac. Today I tried to install my paid version of paragon's NTFS for Mac. I logged in to my paragon software account, saw my product under My registered products and downloaded it. Next to my product was the Product key and Serial number. After rebooting the computer I was prompted with an activation window. I tried copy-pasting product key and serial number and got "The provided serial number has already been activated. Activation is impossible." What is going on? I have allready paid for the product, it hasn't been used in any other computer as I don't own another Mac and haven't given my credentials to anyone. The only other computer it has been installed is my computer with the previous snow leopard installation. I will try to contact tech support tomorrow when I get to the office but from what I have read in the forums it is hit and miss. anyone has seen this problem before?
