Adobe logging out and closing my applications

My adobe account keeps signing out, which results in the application that I have open closing - thankfully it always asks me if I want to save my work, but it’s not ideal when I'm in the middle of something for a client. It was only happening once every so often, but now it seems to be happening every couple of hours. I've tried uninstalling and reinstalling, and tried a number of different other things to try and stop this, but nothing seems to work. Does anyone have a similar problem and no of any way to resolve this? I know when it's going to do it as well because my whole computer slows to a grinding halt.

Any help would be much appreciated!

Thanks
