It wouldn't take very much effort to forward to me, just to rule it out. There is the possibility that for whatever reason my download is corrupting, while yours isn't. (obscure anti-virus settings, who knows). It could be an issue with out of sync CDN, shrug. Files do corrupt in transit... I did some research into compatibility settings... from what I could find (Preferences -> Compatibility). It seems that these settings control how formatting happens when looking at older files, if you can't open it (which I can't without text recovery mode) -- then it does no good for me. I have opened older doc files before without issue... this is a first for me. I found a doc -> docx converter and tried converting it. The converted docx will not open because of invalid characters (corruption?). Well, if you aren't willing that's cool. I'm sure Judi, or perhaps Marvey can give email a shot, and yeah if that doesn't work I'm sure pdf will be fine.
