When I sign in to the Adobe Reader XI (which is the only option that I have to open a pdf document, I will sign in to the Adobe ID sign-in page. After I do this, the "Convert To" box goes "gray" and I am unable to convert the document I have selected.  It was working great for the first week that I used it, but now it doesn't give me the converting option.  I am very frustrated as I have done nothing to change anything, and I was thinking this was so great...now I am just pulling out my hair and do not have the option of calling anyone since no phone numbers are listed. I am VERY busy and do not have time to sit and wait over a half an hour to "chat", which I tried to do yesterday.  All I want to do is very simply, convert pdfs to Word.  I have paid for this and am not getting any help. I am not very savvy when it comes to Adobe this program and Adobe that program...I feel I am being scammed as I do not get simple answers for something that appeared was going to be simple. You can't even call customer service to talk to someone live to help walk you through.
