In reply to Phil1919:
It sounds like you might have created it in Open Office and saved it as "readable by MS Word" - I used Open Office a few times as a "test" a few years back and dimly recall this option - I never had any issues but then I had MS Word on my PC at the time as well anyway.
It's just an idle thought / suggestion / speculative guess.
If you take that USB stick to someone who has MS Word you might be able to open it. In the meantime you may be a bit stuck, but at least check the save options in Open Office.
