Page not found error

I don't know what the hell is going on but this is the second time it's happening. I see a template that i like and try to licence it, then realize i'm not signed in so i sign in and WHOOPS, it's gone. There's an astronaut cat saying "page not found" and i cannot find that template anywhere again. I clear all the cache & cookies but it doesn't help cause the moment i sign in, the template disappears again. And it's not just that one template, i can't licence a damn thing. Even if i somehow manage to open the template, it says "this asset cannot be licenced." BUT WHY? 

Also why do you guys show me a limited number of search result? Like I search for "minimalist magazine layout", why do i only get like 50 results? I really don't get this website..
