Can't convert pdf to Word

I don't know - there is no information in my manage acct. I opened a pdf in Adobe Reader. I clicked the first icon which say "convertpdf files to Word or Excel on line" When you click that, a window comes up beside you file and asks you to select a file, gives a drop down to convert to word or excel, and a blue window to sign up for the subscription. At the very top is a link to sign into your acct. I sign in and I still get the sign up box and a greyed our convert box and convert button.

Thank you
