CSV files and OLEDB in VB.net - Exception with no info

I'm trying to parse a user-submitted csv file in ASP.NET with VB. Here is my function:

Public Function getData() As DataSet
        Dim conn As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Path.GetTempPath() + ";Extended Properties=""Text;HDR=No;FMT=Delimited"""

        Dim cn As New OleDbConnection(conn)
        Dim cmd As New OleDbCommand("SELECT * FROM " + sourceFile, cn)
        Dim da As New OleDbDataAdapter(cmd)

        cn.Open()

        Dim dt As New DataSet()

        da.Fill(dt)

        cn.Close()
        Return dt
    End Function

the error I get is:

System.Data.OleDb.OleDbException was unhandled by user code

The error comes up at the da.fill(dt) line.

Any suggestions?

Every search result that comes up says it has to do using reserved keywords in the CSV file or in the SELECT statement. What's the value of sourceFile?
