Word 2010 shows it is a dot.com file for some reason

Hello, I created a word doc and see the file, but when I try to open it, it comes up as a blank doc with no name. In the file listing, I see the file name and when I last changed it, and the size of the file, but when I click on it, I get a blank page. Another thing, it shows it is a dot.com file for some reason. How can I get the file to come up?
