For what it's may be worth, I would complain to Google first. Though you should be able to download the .acsm file again so it may be worth retrying first. After you download the .acsm file, I would suggest opening it with a text editor and see what it says. There should be a metadata section which should have the title, author, publisher, etc. See sample below.
Code:
<metadata>
<dc:title xmlns:dc="http://purl.org/dc/elements/1.1/">Buying Power: A History of Consumer Activism in America</dc:title>
<dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Lawrence B. Glickman</dc:creator>
<dc:publisher xmlns:dc="http://purl.org/dc/elements/1.1/">University of Chicago Press</dc:publisher>
