I have a Nokia Lumia 822 and backed up my contacts and apps. Reset the phone because of problems I will mention. Didn't help. I read that to get backup assistant to work I should install updates from the store. I can't access the store and I get the same "try again later". I do have a wifi connection. All this started a couple of weeks ago when I noticed that my email wasn't updating.
Right now, all of my contacts are gone and I can't access the backup, which is not making for a very happy camper. Don't know what else to try.....any suggestions---please!?
VZW Backup Assistant is a complete utter waste when it comes to Windows Phone. Should be avoided at all costs.
Try going to Settings and tap on emails+accounts and re-enter your password for your Microsoft Account. The Microsoft Account should be the same one you used when you first configured you phone; before the hard reset.
