Re: for updating my previous service to transfer PDF to words, I have trouble to go into my payment page to update my credit card .

Hi Yingbing_chen@yahoo.com,

I checked your account, your Export PDF annual service has been expired on Oct 4, 2014.

To continue your service you have to resubscribe this.

Kindly refer to this link to purchase the subscription :The Most Reliable Tool to Convert PDF to Word or Excel | Adobe ExportPDF
