Word app for iPad won't allow me to edit document?

I am trying to edit a Word document on my iPad, opened through Dropbox and then opened with Microsoft Word. When I attempt to edit it wants me to convert the format (which I cannot do without upgrading to Office 365.)

The error message I get is "This document has certain edit capabilities that have been locked." I have double-checked and the original file is NOT locked in any way for editing.

It does have embedded fonts - is that the problem?

NY Times subscription on ipad scam?

I subscribed to the NY Times for the ipad at 99 cents a month (for the first 4 months) and it said in the confirmation email to download the app. So I did… Or tried to. The app asked me to pay $119 for a year of access, which I of course declined. Am I missing something here?

Here is the page where I subscribed (I chose web+tablet)

And this is the page that the email link sent me to:
