I opened the Windows Store to download and install an app. I kept getting the "you are not connected to the Internet" dialog box. I was connected though. Checking on Google to fix this I found a MS help page telling me to change a cache file in file explorer to "old" and create a new folder called cache, which I did. I went back to Windows Store and tried to download and install an app. Now it just refreshes the screen. I still cannot download and install an app. Any ideas. Thanks.
