I set up this Windows 8 Installation about 4 weeks ago. the issue with the store appears like over night...

I tried method 1, 2 and 3 as instructed by you but the error remains.

Error Code also refers to a wrong clock and/or time Zone. I checked this and found this to be set correct...

Even after Microsoft Patch Day and installing all updates the error in Windows Store remains and i can not install any apps anymore.

Uppdate of Post 14.02.13
