There seems to be a problem when I am offlining files.

If I upload a file via the web, the file appears locally and I can open it (it downloads and stores it locally)

Files I create locally are synced to the web.

However, changes I make to the local files aren't being uploaded

Files deleted on the web are not propagating to my machine, nor it is working the other way around.

I have tried right-clicking the file that I want and choosing make available offline, but it just stays in the pending state.

My service is not crashing, as can bee seen by some updates going through

I have restarted my tablet (surface pro)

I have a stable, non-metered connection

There are no errors, no progress but only "Pending" for the manual make offline.

This was working until recently, I have installed and uninstalled the SkyDrive application.

I moved all the files onto another drive (Location tab in properties) and then reset the files - they all downloaded (online versions).

Any ideas?
