But go into Preferences/Audio and see if Sonar has it on the list of drivers. if it is,, set it to ASIO,
ASIO does not need to run the wave profiler.
If it is not on the list go to windows audio settings and see if it is listed there.
If not re install the drivers and make sure to follow prompts correctly, some drivers want you to wait to turn on the device at a certain point in the installation
Always use a USB port that is not shared with anything else if possible, and do not change ports.
