I have basically the same problem. After downloading 8.1, a lot of my apps refuse to open, the front screen comes then crashes back to desktop. So annoying, I have uninstalled and reinstalled but still the same problems. Windows Media Player for example , plays audio but not video. Please, does anyone have any ideas?
Yeovil50, welcome to the Windows 8 forum! I am glad you are finding discussions that are addressing your issues. We usually fix them or find workarounds as this site is filled with really sharp users. While you are here, check out the tutorial section, there is a ton of great stuff there.
This to all the posters. I have successfully uninstalled and reinstalled live Start Menu apps and they still work after sleeping. I might have a common thread between the apps and HOMEGROUP issues. Both require the network, HOMEGROUP for connections and live apps for syncing between accounts.
I want to try an experiment:
When you make ANY changes to either live apps or HOMEGROUP, make sure ALL computers that you have in your home network are up and connected to the network. Make sure that they are all working on the HOMEGROUP properly. When uninstalling and reinstalling live apps in the Start Menu screen, make sure that the other machines are able to communicate between each other so that any changes are immediately registered with the other machines.
Frankly, I am not at all sure if this network connection is necessary for changing the live apps but I just happened to have all machines properly connected when I uninstalled and reloaded my live apps and they are still working.
Try this and see what happens.
