Wow, what a lot of great responses. Thanks, all.
To answer a number of questions:
I was using an older version of LO (I just got notified when I brought it up this month that a new version was available). Both versions could not open the .doc file. The 3.5 version I am using now was updated this last weekend (3.5.7.2).
Word 2003 and LO are running on the same machine, running Windows 7.
I didn't consider writing it as RTF and reading it into LO. I'll try that next time.
I'm guessing the LibreOffice folder is the one under "C:\Users\<user>\AppData\Roaming\LibreOffice.
It was suggested I post the file to Nobble. I'm willing to do that, but I don't know what that is. Google doesn't provide anything useful.
I will definitely look into the Bullzip PDF printer (I've downloaded it). I have a PDF printer somewhere (when I bought OmniPage 18), but I can't seem to find the CD. My biggest goal in bringing up this issue was to help the LO developers fix a problem. I was ultimately able to send the .doc file to my work computer and generate PDF there.
Just so you know, I'm not a huge fan of .PDF. The only reason I have to provide .PDF is because the company we use to print the newsletter requires it. Apparently, the .PDF format is a lot smaller, too, so it is what the American Legion suggests. We send the newsletter to about 250 people each month.
I tried the "Open and Repair" option (that was new to me). It came up with a bunch of errors for all the images that were in the document. I then saved the file, but it made no difference. It still doesn't recognize it as a Word document.
I tried "Save as..." with a different name. It was said that this would do a garbage collection. New name has the same problem. It's not recognized as a Word document.
Odt files: Okay, I had a bad experience with OpenOffice. When I contacted the e-mail support group, they said I shouldn't save files on a flash drive. Then someone told me how to unpack the .odt file and fix it with an editor. Okay, that's the last time I wanted to trust the .odt format. I've heard that LibreOffice is much better maintained, but I hadn't trusted the .odt format. I usually save .doc, .rtf or .html formats. I've never had a problem with them. Maybe I should give the .odt format a try again.
Thanks again for all the great suggestions. I've got some work to do to try some of these things.
