tablet pro

Hi, I've been using TabletPro for a while. I use a laptop-tablet running on windows 10. I was in the middle of drawing when I accidentally swiped something on the side bar (can't even imagine which button it was) when it switched to some default layout. When I tried to change it back, it wouldn't change. Nothing I did would make it change. I tried several different layouts- nothing. It's just stuck on default. Updating it didn't work. Trying to make a new one in the manager didn't work. I'm not sure what to do. Any assistance is greatly appreciated. Thank you!
