Hi Skip,
Great to hear the new Yamaha Mixer Is working well for you. I used to have a pair of Behringer condensers (I believe they were the C-2) and they worked great on acoustic guitar!
Since you're running Windows, if you're ever looking to try a new DAW I recently found that Sonar is now free! It's now reverted to it's original name Cakewalk due to a company buyout but the software appears to be the same:

I loved that DAW back in the day and did a ton of project on it. The workflow and plugins it comes with are crazy!
Also, if you're new to the recording world, here are some articles on the topic you may find useful:

Hope these help and best of luck with your recordings! I look forward to hearing them soon
