Skydrive stopped connecting on Windows 8.1 pro

Hello,

I am encoutering a problem that my Windows 8.1 pro stopped sync today (it was fine until now). I am receiving a message under PC settings - SkyDrive - File storage that "Sorry, we couldnt connect to SkyDrive. Please try again later, or go to SkyDrive.com to change settings". As I proceeded to my account on SkyDrive.com, everything is normal.

Some things you might ask.
1. My Windows 8.1 pro is logged in with the same windows live account.  Unter PC settings- Accounts I can only pick "Disconnect", which means I am properly logged in as usual.
2. I have another Windows 8 pro laptop running a desktop client version of Skydrive, which is still working perfectly.
3. I cannot possibly delete and reinstall SkyDrive on windows 8.1 pro since I have never downloaded any desktop client.
4. Because there is no desktop client on windows 8.1 pro, I cannot change anything on the web version of SkyDrive under PCs on the left (I actually dont see my windows 8.1 device under PCs since the first day I am using it).
5. My windows 8.1 is connected to the internet properly, no proxy.
6. SkyDrive Sync Engine continues to run and doesn’t crash at all.
7. The issue happens on all folders and files.
8. No any sorts of error icon or pop-up.
9. Cannot possibly reinstall since I have never installed Skydrive client. it just came with windows 8.1 pro.

Can somebody help me please.

Thanks
