Hi Elir,
We are sorry to hear about frustrating experience.
I have looked into your account information, and found that the Adobe Export PDF subscription is registered to your account but its not active. There seems to some issue with the payment which is causing trouble accessing the services.
We request you to follow the instructions suggested below and contact our billing support team. They would go ahead and fix the payment issue.
1- Refer to the link Contact Customer Care
2- Select Account issues


3- Show me my contact options.


Adobe Export PDF https://helpx.adobe.com/document-cloud/help/using-exportpdf.html is an online service that you can access via web browser- https://cloud.acrobat.com/exportpdf
You can also use the services through free desktop version of Adobe Reader- Adobe Acrobat Reader DC Install for all versions
2-You just need to “Sign In” using the email (Adobe ID) under which you have subscription registered.
4- Please ensure that you are working with Adobe Reader DC not Acrobat DC to access PDF Pack and "Signed In" using correct email.
