I have a serial number but it wont let me access the system?

I paid $199.00 and tells me Im only using the free version???

You paid that for what?  Acrobat perhaps?  Have you downloaded & installed it?  Have you activated it with your serial number?

And what exactly do you mean by "free version"; can you give us the exact message or a screenshot: https://forums.adobe.com/thread/1070933
