First freeze/lockup just now

I just flew KFLL-KDFW, ( fdreamteam sceneries), as soon as I landed and reverse kicked in my saitek yoke pro stopped responding and so did the panel gauges . The plane stopped and started going backwards and I could not stop it. I hit a couple of times f1 and it eventually came to a halt. Using the keyboard I was able to exit the runway but the instruments were stuck. I took a picture so you can see what I mean. Thanks Vic
