What does the CSV file look like if you try to read it with Notepad?
Remember that a CSV is a plain text file, with Comma Separated Variables.

If the CSV file itself is OK, how were you trying to open it from Excel
2007? Were you just trying to double-click on the file? If that doesn't
work, the other options which I would try with Excel 2003 are File/ Open or
Data/ Import External Data/ Inport Data. If you still don't know your way
around Excel 2003 to 2007 command mapping, try

I have a Membership roster that I would like to convert to a .csv file.
The
Membership intranet allows me to click on "Create a CSV", and up until I
got
a new computer this past Spring, I was able to get the file without any
problems.

I have pruchased and installed Microsoft Office and Student 2007, but I
still cannot run the file.

Does anybody have any suggestions??
