Well long story short, I have a lot of add-ons, but haven't installed them yet. I've had this problem in the past, and I've just recently switched to a new computer. I'm doing a fresh start with everything (nothing is being transferred), so as of now I do not have much on this one. I mainly use FSUIPC for the FSXFlight program, but I have not installed it yet. I was installing things slowly so I could try and identify the issue I was having with COMM/NAV. So I don't have much on there, and when ever I remove FSUIPC, everything works fine, then reinstall it, and the issues come back. I've talked with Carenado, and they say they don't have any idea and just to remove FSUIPC, but then I can't use FSXFlight which I use a lot. So that's where I stand on things. Who knows, I guess I was just hoping I was missing something easy. Thank you for your responses!
