How do you contact customer support?

I purchased Reaktor 6 yesterday and used the serial number.. everything was working fine. today it asks for my serial number again but it is not on my product list anymore… I have the purchase info attached to my account but the serial number info has vanished.

What is your OS ? , Generally then you are expected to download and install latest version of Native Access for your OS.

Else then often then such problems are because people log into the wrong account , you should be able to see any serials connected with your account on the MY PRODUCTS, SERIALS, AND DOWNLOADS page , listed as either Not registered or as Registered Products , just make sure that you are logged into the same correct account in Native Access.

If the product is completely missing from account page then alas only Account Support can help you.

If the product lists as registered on account page but does not show in Native Access or only shows as Demo then you can try the following Trouble shooter here : My Products Are Showing As DEMO in Native Access , especially '2. Your activation fails because of corrupted or missing activation tokens' and '3. You have corrupted XML files' (delete both NA XML and Reaktor product XML) then restart computer and log in again to see if that helps
