A few of our engineers keep having the same problem. Once we navigate down into a subfolder we can not naviate back to a folder above it. If you click on a folder higher in the file path - next to the home button - the screen loads then drops you right back down into the folder you were in. It's almost as if the page is caching and refusing to navigate away from the current folder.
Please help! The only solution we have come up with is restarting Creo, but once you move into a subfolder you are stuck there. So to work in another folder you have to restart again.
