Slow loading time

The loading time is so slow the system is becoming unusable. I’ve been trying to get the system to load on my computer for over an hour today. The other day it took 45 minutes. The computer is 1 year old, 32GB of Ram, 64-bit OS, intel core i7, 1 TB storage. Once I finally get the system to load, the Zwift bike and steering connects but says no signal. Then I have to reboot and start over. When I finally get the system to connect, I select a route and again wait for the system to slowly load. 1 hour and 20 minutes later my ride is starting.
