Lynxen

I had to redownload the app due to a revoke, and I have all my information for my account and purchase, but when I redownloaded the app, it is stuck on a page that says “Activate.” When I press the button, it brings me straight to purchasing another account, with no section to put in my information that I have already bought everything. I redownloaded the app using the email I was sent, but I’m stuck. Any way to fix this?
