Hi Laurolyna,

We have checked your account information, and found Adobe Export PDF subscription registered to it. What you are looking for can not be achieved with the Export PDF subscription.

Because Adobe Export PDF is an online Adobe Document Cloud service. With it, you can easily turn PDF files into editable Word, Excel, PowerPoint, and RTF (Rich Text Format) documents. Using Adobe Export PDF

As try67 said, you need to subscribe for Adobe Acrobat DC for that. DC Help | Acrobat DC User Guide 

Hope this helps.
