Question about Outlook Express

Hi there

Since updating to Win8.1 on my tablet (Lenovo ThinkPad tablet 2) over 2 weeks ago I've been totally unable to get sky drive sync'd. Sky drive has always worked flawlessly with the old desktop app, but this new situation is wholly unsatisfactory and is making me very annoyed. It seems to be a problem affecting many people, is there any way to resolve it? Google can't seem to offer anything useful.

Here are the symptoms

1. Firstly, not all my files will actually appear in view in the Modern App, let alone download. I have tried to check the all-offline option but it is greyed out. I have tried this in explorer, as well as on the Modern App.
2. The Modern App has a kind of status page, this  continuously has little black dots travelling across the top of the screen as though processing something but nothing ever changes.
3. Also in the app, the notification is stuck on "downloading 222 options" for DAYS. All the files in view say "completed" and won't refresh.

PLEASE how can I reset the skydrive app? I've tried switching to a local account, emptying the skydrive folder and then going back to my MS account but it just seems to remember everything!

It's starting to get me very angry. Up until now I've loved my tablet, but this is really starting to drag me down.

On my main PC I've had none of these problems, I can just assume I got lucky with it.

Any ideas? I'm on the verge on uninstalling 8.1 so I can have the old skydrive app back. I'm a bit helpless without my documents! In case it's important, I moved my skydrive folder to a micro SD card D drive.

Thank you in advance for any help you can offer

Mike
