Recording Device Settings and Project Sample Rate

Hi Folks. Each time I try to engage the software, I get a message that indicates- “Please check recording device settings and project sample rate.” What does this mean and how do I correct it in order to use Audacity? Thanks so much!

Please see this FAQ from the Audacity Manual: http://manual.audacityteam.org/o/man/faq_errors.html#sound_device
