Thanks for the replay. I've been there and all I see is Would you like to renew this license? Even though I paid for it already. I tried searching on that web page for the word license and none of them have the number attached.
You have an active JomSocial PRO license. Please check that page again to get the license number. I'm showing you an image of where the license ID is located:

If you can't find it send me a snapshot of what you are seeing on that page.
