2 installations on a PC Desktop and a PC laptop

I bought Audirvana + and installed it on my Desktop hooked up to my Denon Receiver. I went to hook it up on my laptop to access my Yamaha Receiver upstairs. I got a free trial but it said my login info was incorrect. I double and triple checked and all was good. It should have worked? I can hook up my Yamaha from my desktop location but then I have no control upstairs. ???
