Wilco CRJ-700 Troubles

Hey I've been trying to fly my checkride for United Virtual, and I'm trying to fly the Wilco CRJ-700. The problem I am having is that when I select Altitude hold, then push the altitude hold button on the autopilot, the plane won't climb, just descend. I've tried to trim and pull up but it will just go back to about 5 degrees descent. Everything else I believe works, but I can't fly my whole checkride by hand. Also, I tried installing a panel for the POSKY CRJ-200 and all I have are blank gauges. I'm getting quite irritated!
