last week I updated my windows 8 to windows 8.1. After update I signed in to same account as before but this time skydrive is not showing any files neither it is uploading any file form my laptop. When i open the app it shows SkyDrive is temporarily unavailable at  right-top corner.

And even files from MS-Office are also not uploading to skydrive. 
Furthermore I am facing same problem in uploading files from my skydrive app form windows 8 phone .

Please let me know how to sort it out.

Thank You
