For 7.0, the latest version of DAQmx that you can use is
8.1. Since you just bought the 6008, you probably have a much newer version installed. Uninstall the current driver, download 8.1, and install that. You should then have a Measurement I/O>DAQmx palette. On their will be the DAQmx functions and the DAQ Assistant. You should also have numerous examples to look at.
