Have you tried "resetting" your office app on the device? Are you trying to acces the files from the Office app or the skydrive app?
I'm having fits with both and just discovered that my insalled skydrive app hasn't updated on its own. It was still v1!
Before resetting Office you'll need to email each and every file to yourself to remove it from Office on the phone. Basically ensuring that the files are either ON skydrive - or can be sent to skydrive - but are defintiely NOT on the phone - otherwise you'll lose them all completely!
Then go to Settings on the phone, applications, locate Office and tap Reset.
THen go to you applications list and tell skydrive to update, I think I didi this with just a long press and selected updatw, or maybe I went to marketplace on my PC and told it to update, I really can't remember - I've pulled an all nighter trying to sort this out on my own device and STILL skydrive tells me it can't read the video file that it downloads from itself and which was uploaded from the phone!
Am basically resigned to the fact that apparently you can UPLOAD a video to skydrive and view it on a PC, but you can't bring them back to your device - so what good is 25 GB of Cloud storage to keep your device free if the device can't read it's own files after they've been stored on Skydrive?
ALso am noticing that with Excel, once the file gets opened on device and then edited - that it saves as yet another file on skydrive! so my "original_file.xlsx" file has now become "original_file 1.xlsx" and then a second editing of "original_file 1.xslx" turned it in to "original_file 11.xslx" or sometimes "original_file 1(1).xslx" :straight:
Isn't this just supposed to work? Aren't supposed to be able to send our filed to sky drive then retrieve them for editing or sharing?
Well, at least I have 25 GB of space to use up for all my self replicating files!
