You didn't post your code, so it's impossible to say what may be the problem, but the following works to read the contents:

Note: Since some of the columns have text information, the stock "Read from Spreadsheet File" in LabVIEW 7, which is what you said you're using, will probably be inadequate for you. You probably want to read the contents in as a 2D array of strings. You can easily modify the stock "Read from Spreadsheet File" VI to use a 2D array of strings. Just make sure you don't overwrite the one that comes with LabVIEW.
